ABSTRACT

By the use of high performance solid-state infrared

emitting diodes, matched infrared detectors, and a single

chip 8-bit microprocessor, an in-process infrared den

sitometer has been designed and constructed. The device is

capable of recording the build-up of optical transmission

density on an exposed film sample as it develops, with no

effect on the normal development process. The most novel

feature of this system is a special development chamber with

eleven built-in infrared densitometers. These densitometers

are located as to read every other step of a standard Kodak

#2 step-tablet exposure, and to allow the passage of dev

eloper across the film sample.

As an example, every other step of a 21-step exposure

can be measured to produce a series of eleven density

readings in approximately 22 milliseconds. These measure

ments can be repeated from once every second to once per

minute at any time during the development process. The

microprocessor that controls the infrared densitometer has

memory capacity to store the data required to generate 187

complete D-Log exposure curves. At the completion of pro

cessing, the density readings recorded earlier are available

for user viewing on a large seven segment digital display

system, or can be reproduced on a line printer.

D-Log exposure curves obtained from the device are in

good agreement with curves obtained by conventional means.

The device has a useful range of 0 to 3-00 density units

with an accuracy of +/- .02 density units.

INTRODUCTION

The design and construction of a device that would allow

for the procurement of densiometric data from a sample of pho

tographic film as it developed has been the subject of numerous

thesis projects at the Rochester Institute of Technology. Some of

these devices have been constructed, and feasibility proven, but

their usefulness was extremely limited due to their primitive

nature. The purpose of this thesis is to tie all previous

efforts together in the design, construction, and testing of a

completly new, workable, and reliable in-process IR

densitometer.

The conceptual requirements for IR densi tometery have been

well known for years, but prior workers have either lacked the

technology, or the expertise to construct a truly significant

device. This project makes use of state-of-the-art technology

along with industry standard development and assembly techniques

in its design and construction. Therefore, the general aim of

this project is to produce a research instrument of the highest

possible caliber to allow those qualifed to study photographic

processing.

Of the many possible uses for this device, induction

period studies have received foremost consideration in its

design. The ability to monitor changes in the rate of develop

ment and to know exactly when the developer makes actual contact

with the emulsion are absolute necessities when attempting to

determine the length of the induction period. This is where the

conventional method of arresting development fails. The

procedure becomes inaccurate at short development times. The IR

densitometer, however, has been designed tomonitor density build

up on a second-by-second basis, thus providing an accurate record

of exactly how the film sample developed.

Prior Work:

Conceptually, the design of an in-process IR densitometer

is quite simple. All that is really needed is:

1 .) A source of infrared radiation to which the film being

investigated is insensitive.

2.) Some method of directing this radiation through the

developing film sample.

3.) The collection and detection of the radiation after it

has passed through the sample.

4.) A method of relating the detected signal to some type

of optical transmission density.

5.) An output system which will deliver the desired sen-

sitometric data to the operator in some convenient

form.

However simple this may sound, it has taken almost fifteen

years and the contributions of many individuals to reach the

point where all prior efforts could be concentrated into the

construction of a truly significant and useful in-process IR den

sitometer -

One of the earliest uses of infrared densitometry was made

in 1953 by Fortmiller andJamesl

. They used a device that would

be the predecessor for future designs at the Rochester Institute

of Techonolgy. Their apparatus was used to study the kinetics of

development of a fine grain motion picture positive emulsion by

vanadous ion.

The first attempt to actually build such a device at R.I.T

was made by Hughes in 19642- As it was only a B.S. thesis, the

project was somewhat limited in scope, but the conceptual

feasibility of in-process IR densitometery was shown.

Hughes IR source consisted of a tungsten display case lamp

filtered with a Wratten No. 70 filter. The radiation was

directed onto a developing sensitometric exposure fastened to the

bottom of a plastic tray- From the other side of the tray, 84

plastic rods piped the IR radiation to a large collar with

a single L-shaped light pipe mounted in the center- This L-

shaped rod then had a silicon photovoltaic cell located on axis

so as the rod was rotated, it could scan all 84 pipes and direct

their output onto the single photocell. The pipes were scanned

by the rotating rod at such a rate as to produce 40 charac

teristic curves per second. The output of this cell was then

logarithmically amplified and displayed on an oscilloscope

screen. The screen was photographed by a single frame motion

picture camera and the resulting images could be projected onto

an empirically determined transfer curve relating wet IR density

to dry white light density.

The problems encountered in this system were numerous,

the major ones being non-uniformity in transmission between the

light pipes and poor photocell sensitivity at high densities.

However, the five neccessary sub-systems called for in the earlier

paragraph concerning conceptual simplicity were present.

1.) IR source: tungsten lamp and Wratten filter.

2.) Radiation through-put: plastic light pipes.

3.) Detection: rotating silicon photocell.

4.) Relation of system output to density: log amp and

transfer curve.

5.) Display: oscilloscope, movie camera, and projector com

bination.

In 1970, a second endeavor was made to construct an IR

densitometer by Hisler and Casinelli3. The five major sub

systems of their design can be outlined as follows:

1.) IR source: one six-volt, fifty watt tungsten lamp

filtered by three Kodak No. 29 Wratten filters.

2.) Radiation through-put: single emitter/detector com

bination. Developing s ens i-s trip wasmechanically moved

through IR beam by being mounted inside a revolving

plastic cylindrical tank. Method of rotation was a

phonographic turntable which would produce one complete

scan of the sensi-strip every .77 second.

3.) Detection: single photomultipler tube from a Macbeth

TD-102 densitometer with an S-4 response.

4.) Relation of system output to density: output of TD-102

fed directly to oscilloscope, logging and scaling per

formed by TD-102 electronics.

5 . ) Display: oscilloscope screen with copies being made by a

Polaroid scope camera. Type 107 film was used.

The major problem with this system was the mis-match in

peak spectral responses of the source/detector combination. Add

to this the necessity of three Wratten No. 29 filters to prevent

film fogging and it is understandable why no useable output

was obtained.

A third series of design improvments were proposed and

implemented in 1971 by Beaupre and Jasper1*. Their system

consisted of:

1.) IR source: a single 120-volt, 500 watt Sylvania EHA

tungsten-halogen projector lamp filtered by Kodak

Wratten filters Nos. 87 and 87C

2. ) Radiation through-put: same rotating turntable arrange

ment used by Hisler and Casinelli.

3.) Detection: Hewlett-Packard PIN photodiode.

4.) Density transformation was performed by a solid state

logarithmic amplifier.

5.) Display was same as that used by Hisler and Casinelli.

that is, an oscilloscope and Polaroid scope camera.

This device was tested with Eastman Kodak Fine Grain

Release Positive Film, type 5302, developed in DK-50 and D-76.

The results of their experiment demonstrated good agreement bet

ween conventionally obtained characterstic curves and their IR

obtained ones . However, beyond a density of 2 .5, curve deviation

due to non-linearities in their amplifier became significant,

thereby limiting the useful range of the device.

The first attempt to use the above device as an actual

research tool, and not a single project in itself, was made by

Turbide and Williams in 1972^. They investigated the phenomenon

of lith or infectious development. Film type used was again

5302 and ortho Kodalith type 3, 2556. No modifications were

effected upon the device and the only significant contribution of

this endeavor was to simply repeat those results obtained by

Beaupre and Jasper-

In an attempt to increase the useful density range of the

instrument , Turbide andWilliams tr i ed r emov ing the ant i -halation

backing of their sensi-strips before development. But even with

this, the device gave linear results only out to a density of

about 2.4.

A more comprehensive write-up and representative curves

are contained in an article written by B.H. Carroll^

summarizing the work of Jasper, Turbide, and Williams.

Technically, the paper deals little with the construction and

operation of the densitometer, but rather with the subject for

which the project was performed; photographic chemistry-

Industry references to IR densitometery are scarce, but

two major ones will be mentioned here in the hopes of

demonstrating that the concept is not merely an academic

curiosity. In 1 966, Spitzak7 made use of solid state IR emitters

and silicon photodetectors in a film scanning system. The ulti

mate purpose of the system was to scan photographs of planets

obtained by spacecraft , digitize the signal , and transmit them to

earth. As a side note, the author mentions the possibility of

using such a system to perform density measurements before fixing

the film to determine the degree of development.

More in keeping with the scope of this project, Keemink

and Van derWildt

designed and built a device which they called

a gammascope. The main intention of this project was to monitor

the density build-up of a piece of film while it was developing,

and then to arrest the process when a certain value of gamma was

reached.

The conceptual layout of this system is very similar to

that under consideration in this paper- An array of discrete

IREDs (infrared emitting diodes) with matching discrete photo

cells situated such that twelve positions of a continuous density

wedge (maximum density of 2 .00) , could be scanned during develop

ment . The output of the photocells is then electronically trans

formed into density values by a logarithmic amplifier- From

here, the materials characterstic curve is displayed upon an

oscilloscope screen as a series of discrete "dots". Gamma could

then be determined by fitting a line through the linear portion

of the curve and calculating its slope.

It is within this body of work where the first mention of

problems involving the Herschel effect is encountered.

Decreases in density were stated to occur when repeated scans

were made in the earliest states of development. It is at this

point when latent image centers are not yet rendered fully deve

lopable and are most susceptible to deterioration by IR

radiation. This condition can be further aggravated by the use

of very dilute developer solutions. The authors suggest that

8

this problem can be avoided by performing no scans during the

first minutes of development. However, one of the most important

design aspects of an in-process IR densitometer is to gather sen-

siometric data during precisely the first moments of development

in order to study induction effects.

The most recent work in the field of IR densitometery was

performed in 1976 by Piskacek9. His M.S. thesis was a natural

progression of previous work leading up to a final proof of

in-process IR densitometry feasibility.

The body of his project dealt with the design of a special

chamber which would allow a sensiometrically exposed piece of

35mm film to be scanned by IR radiation while it developed. His

specifications called for an array of eleven solid state IR

emitter/detector combinations to be mounted within the chamber to

facilitate density measurments being taken from a 21 -step sensit-

ometric exposure.

Not only was the chamber designed, but the materials

called out by his plans were tested for their suitability in a

developer environment (e.g. extreme excursions in pH) . Also, any

material which was to be used in the transmission of IR was

tested for its optical properties and possible attenuation in the

IR.

Although Piskacek was unable to actually build his

chamber, he was able to bench test a small portion of the

electro-optical system. Using an IR emitting diode, (Monsanto

ME5) and a solid state detector, (UDT-500, effective area .05

cm2) , he was able to obtain a linear correlation between unfixed

IR density and fixed out white light density. Agreement was good

out to a maximum density of 2.00.

General Design Considerations:

Piskacek's work in 1976 was one of the last design steps

necessary for the construction of a truly significant and useful

in-process IR densitometer. Very little was said, however, about

the design of a working densitometer from a systems approach.

Piskacek used a simple block diagram point of view for detailing

how he thought the remainder of the densitometer should be con

figured. In all actuality, he really intended for the remaining

work to be carried out by someone else, and purposely left any

electronic designs vague.

Picking up where Piskacek left off, a complete IR den

sitometer system can be generalized. His selection of IR emit

ters and detectors mounted in a specially designed development

chamber would produce eleven discrete optical transmission

signals. Some of the most important design considerations for

this system are that these signals be generated quickly (on the

order of milliseconds), accurately (within +/-.02 density

units) , and over a density range of0to3-00- Another important

consideration is an efficient and convenient method of storage

and display of density data. The old method of photographing an

oscilloscope screen would not be suitable for the system being

considered here.

To meet the above generalized requirements, a single chip

8-bit microprocessor has been selected as the system controller.

Microprocessors are ideally suited for the rapid control,

storage, and display of data. For this particular system, the

microprocessor will control the sequential pulsing of the eleven

emitter/detector pairs to generate eleven optical transmission

signals. By the use of an analog multiplexer, it will direct

these signals to a high-performance logarithmic amplifier, and

then put them into digital form for input to the microprocessor.

The output system will consist of a light emitting diode display

10

of the actual density values, or permament records of density

information can be generated on a line printer.

The overall design philosophy is to construct a device

that can be used as a research instrument by scientific person

nel.

IR Densitometer System Description:

The design of the in-process IR densitometer can be broken

up into three major functional groups. These three groups are:

data acquisition, data management , and data output. Although all

groups are under total control of the microprocessor, this func

tional grouping will aid in understanding the system as a

whole (see figure 1).

Data Acquisition:

The major component of this sub-system is the development

chamber. The chamber is a precisely machined block of stainless

steel designed to hold a strip of 35mm film in registration

against eleven solid state IR densitometers while developer is

pumped across the sample. The chamber is made up of two matched

sides that mate to form the development cavity. It is connected

at the bottom by a hinge pin (see figure 2) and sealed at the top

by a locking pin. The top section contains the eleven IR

emitting diodes (General Electric LED55C, see appendix 4 for

complete specifications). Each diode is mounted in a small tube

with a lens at the end (f=5mm). This assembly is mounted in a

guide hole behind a plastic window and focused onto its companion

detector below. The bottom section contains the eleven IR detec

tors . They too are mounted behind a plastic window and when the

chamber is sealed, are in perfect registration with the emitters

on top and create eleven discrete, solid state mini IR den

sitometers. The detectors (UDT-450's, a photodiode-operational

amplifier combination, see appendix 5) produce an optical

transmission signal directly. These eleven outputs are fed into

an analog 16-channel multiplexer. A multiplexer is simply a

16-position switch with one common output. The switch selected,

however, depends on the state of four address lines into the

multiplexer. In this way, the output of an individual detector

can be selected and processed within the array of eleven. Due to

this one-at-a-time selection of the detectors, the term "arrayscan"

becomes useful in describing how the eleven

emitter/detector pairs are sequentally pulsed to make a complete

reading of the optical transmission density (commonly called

"density") of the developing film strip. To take a density

measurment of the film sample, the first emitter/detector pair is

switched on, a reading made, switched off, the second pair turned

on, etc. Hereafter, a complete set of density measurments for a

film sample will be called a "scan". A scan produces eleven den

sity readings and takes approximately twenty-two milliseconds to

perform. Keep in mind that all scan timing and signal processing

is performed under the direction of the microprocessor.

From the multiplexer, the analog transmission signal is

fed into a logarithmic amplifier (see appendix 6). Here the log

of the input voltage is taken to produce an analog transmission

density signal. This log amplifier has been scaled to produce a

two volt change in output for a ten times change on the input.

In other words, a sample density of 1.00 produces an output

voltage of 2.00 volts, a density of 2.00 gives an ouput of 4.00

volts, etc. This signal becomes the input to a 10-bit analog to

digital converter. The output of this device is a 10-bit digital

density signal, which is in a form ready for input to the micro

processor -

These components make up the data acquisition group.

Note that any component that operates on analog signals is con

sidered part of the data acquisition system. Once the signal

becomes a 10-bit digital word, it enters the digital domain and

remains there until final output.

15

Data Management:

The data management sub-system is made up entirely by the

Intel SDK-85 single board computer (see appendix 7) . This board

contains the Central Processing Unit (CPU) or what is better

known as the microprocessor. It also contains all memory ele

ments, input/output devices, time bases, and display controllers.

A complete description of how this computer works is contained in

the SDK-85 System Design Kit User's Manual #9800451B.

The reason the IR densitometer was designed to be

controlled by a computer is twofold. Of the many problems

encountered in earlier IR densitometer designs, accurate timing

of the density scans and a convenient means of data storage and

display were two of the most difficult to solve. These are

areas, however, where microprocessors excel. They operate on a

very accurate crystal time base, and are able to store large

amounts of data very quickly.

Once the 10-bit digital density word leaves the A/D con

verter, it is brought into the SDK-85 bus structure through two

8-bit I/O ports (see figure 3)' The system bus is the means by

which data is transported within the computer itself. This data

is then immediately stored in random access memory (RAM) for

later processing. As each scan produces a burst of eleven den

sity readings, this data is stored as eleven 10-bit word blocks.

From RAM the data is processed further (i.e. scaled in accordance

with certain calibration procedures) and becomes ready for out

put .

Data Output:

For computer data to be of any use, there must be some

convenient method to present this data to the user in the real

world. For the IR densitometer, the user has three methods of

data output. The first output system is for the immediate

viewing of density data. The computer can be directed to

display any density scan on a 33-digit light emitting diode (LED)

display. The system will display all eleven density readings

from a single scan. The format for a single reading is X.YZ.

That is, each reading is accurate to three significant figures,

i.e., with a resolution of +/- .01 optical density units.

The second method of data output is through a 40-column

line printer. Any set of density readings on the LED display can

be reproduced on the line printer- This is to allow the user to

generate a permanent record of any particular density scan. For

a complete description of these two output modes, please consult

the In-Process IR Densitometer User's Manual .

A third method of data output has been partially provided.

Connectors have been installed to allow for the connection of

this computer to a higher level computer. With this type of

inter-connection, data could be transferred to the higher level

system for even more processing of density data. As an example,

computer graphics could be used to create D-Log E curves on a CRT

screen. Completion of this interface depends on what type of

higher level computer is selected, and therefore has been left as

a separate project.

Data Acquisition System Analysis:

Information within the IR densitometer can be either in

analog form or digital form. An analog signal is a voltage that

can vary infinitely over a given range. A digital signal is a

voltage level that can vary only in discrete steps. This par

ticular digital system is binary; the voltage signal has only two

levels, low and high ("0"and "1"). When working with digital

systems, very strict and well known rules of logic apply. For

analog systems, however, events are not so well defined. It is

the intent of this section to provide a set of equations that

will describe the operation of the analog system within the IR

densitometer .

Figure 4 shows the physical relationship of the com

ponents that make up a single densitometer- Figure 5 gives a

schematic representation of the same densitometer, alongwith the

other components that make up the analog system. The figure pre

sents an ideal system configuration where all devices are con

sidered to be perfect and introduce no errors.

The IR emitting section consists of the IRED, lens tube,

and lens which is used to focus the output of the IRED onto the

detector surface. The power per unit area incident on this sur

face is the irradiance and is expressed as H watt/cm2. The

detector surface has an active area of A cm2and a responsivity

of R amp/watt. The peak output of the IRED and peak responsivity

of the detector are so well matched that no wavelength term need

be included in the calculations that follow.

With these terms now defined, the current generated by the

photo-diode is given by:

IT = (T)(H watt/cm2) (A cm2)(R amp/watt)

The output voltage of the operational amplifer is:

^T = Rf'-^T

where Rp is the feedback resistance in ohms.

Now the sample transmission T, can also be expressed as a

density:

T =10~D

Substituting:

VT =H-R-A-RF-10-D

The irradiance, responsivity, active area, and feedback

resistor all remain constants, and can be collected into the

term C.

VT =C-10-D

Neglecting any effects from the analog multiplexer, this V^ is

input to the logarithmic amplifier- The transfer equation for the

log amplifier is:

VD = -K=Log(Is/IR)

where 1$ is the signal current and IR is a reference current. To

place the expression in voltage terms:

Is = Vx/Rs and IR = VR/RR

Substituting:

VD =-K-Log(VT/VR RR/RS)

22

Vf is known and can be substituted:

VD =-K=Log(C-10-D/VR RR/RS)

VR is a precision reference, and therefore a constant.

RR and R$ are resistors; also constants and can be removed.

Let:

M = C-RR / VR-RS

And:

VD =-K-Log(M-10"D)

VD = K-D - K-Log(M)

Notice that -K-Log(M) is just another constant, therefore

combine it form N.

Lastly:

VD = K-D - N

This analysis shows that the output voltage of the log

amplifier is simply a scaled version of the film sample density,

plus some additive constant, N. For this particular system, K

was made to equal 2.0. The constant N presents no problem as it

can be nulled nearly to zero by an external offset adjust on the

Log amp. Any remaining offset error can then be removed by soft

ware calibration routines. Therefore:

VD = 2-D - N

23

The log amplifier is the last element in the analog

system. From here, V^ is converted to a 10-bit digital word and

then enters the digital system.

In reality, all the components of the analog system are

non-ideal and each has a certain amount of error associated with

it. The most critial types of errors are voltage offsets and

non-linearities. Within the entire system, only two devices have

these problems to any appreciable degree. They are the

operational amplifiers and the logarithmic amplifier. The

remaining devices introduce errors so small as to be negligible,

or they cannot be characterized. Figure 6 again shows the analog

system configuration, but this time the two major sources of

error are shown as offsets D-| and D2 .

An ideal op-amp would have an output voltage of zero volts

when the photo-diode connected to it was in complete darkness.

This, however, is not the case. Due to temperature drift, noise

pick-up and other effects, a trim pot has to be connected to each

amplifier to zero out these offsets. No offset adjustment is

perfect, and the remaining offset is called D-] .

The output of the op-amp now becomes:

V-p = Rp-Ix + D-|

The operation of the logarithmic amplifier is also non-

ideal and has two types of errors associated with it. The first

is an offset D2 which is present for similar reasons as in the

op-amp. The other type of error is something called Log

Conformity Error (LCE) . LCE is the error expressed in the

output's ability to perform an accurate logging function of the

input. Hence the LCE is always expressed Relative To Input

(RTI). For the Analog Devices log ratio amplifier:

LCE = +/- M, RTI

These errors manifest themselves in the transfer equation

for the device as:

VD =-K-Log(1.01-(VT/VR RR/RS))+D2

Substituting in for V-p:

VD = -K-Log(1.01-((C-10"D

+ D-])/VR RR/RS) )+D2

=-K-Log(1.01-C-RR-10-D/VR-RS + 1.01-RR-D-|/VR-RS)+D2

=-K-Log(C-RR-10"D/VR-Rs

* (1-01 + 1.01-D-|/C-10-D) )+D2

Since:

M = C-RR/VR-RS

Then:

VD = -K-Log(M-10~D-( 1.01 + 1 .01 D1/C-10-D))+D2

= -K-Log(M-10~D)- K-Log(1.01 + 1 .01

-

D-] / C 1 0~D )+D2

From ideal case :

VD = -K-Log(M-10"D)

= K-D - N

26

Therefore, in the general case:

VD = K-D - K-Log(1.01 + 1.01-D<|/C-10-D) + D2 - N

Ideal Error

Term Term

The output voltage of the log amplifier can now be

expressed as the sum of an ideal term and an error term. Note

that the error term is not a constant but rather a function of

the film sample density. Note also that if the LCE were 1.00

(ideal) and the op-amp offset D-| were zero, the error term would

vanish and only D2 would remain.

This error analysis details which sources of error are

important and which ones are not. The offset errors D2 and N are

simple additive constants and can be easily subtracted out later

by a computer software routine. The LCE and the offset D-] ,

however , are not insignificant . They produce a logarithmic error

which is a function of density. It is extremly difficult to per

form logarithmic functions with assembly level software, there

fore, these errors cannot be removed by any calibration routine.

What must be done is to minimize the effects of these errors.

Log Conformity Error is fixed. It will always be present and

cannot be removed. On the other hand, D-| can be made to be very

close to zero. Any error introduced by the offset D-| becomes

apprecible only at higher densities . For this particular system,

D-| can be kept to about + 3 millivolts. This along with the LCE

translates into an error of about -.06 density units at a sample

density of 3.00. This is indeed acceptable, and the

error is almost non-existent at lower densities.

Figure 7 is a graphical representation of how detector

offset errors affect density measurements. Input density is to

be considered actual sample density, while output density is the

density reported by the system with the above transfer equation.

The numbers used in that equation for the generation of figure 7

are based on actual constants used in the physical system. Only

positive offset errors are shown in the figure as negative off

sets have a completly different effect on the system. This is

because the physical log amplifier produces undefined output

voltages for negative inputs. What really tends to happen is the

amplifier output will saturate (go to maximum output voltage,

which is about 14.3 volts). If the analog to digital converter

were able to resolve this voltage ( 10.00 volts is it's maximum) ,

the computer would think a sample density of 7.0 were being read.

Therefore, to prevent such events from happening, the offset null

trim pots for the eleven detectors are purposely adjusted to pro

duce a positive offset of a few millivolts at all times. This

precludes the possibility that the detectors might drift and pro

duce a negative output. This method, of course, introduces some

slight error, but to have a density reading that is somewhat

lower that reality, is considered far better that a reading of

3.0 being reported as 7.0.

29

Experimental Verification:

The purpose of this section is to demonstrate two of the

most important operational capabilities of the IR densitometer-

They are:

1.) The ability of the device to relate wet, un-fixed IR

density to dry, fixed-out diffuse density in a linear

fashion. Also that for the same development time, wet,

un-fixed IR D-Log exposure curves are in good agreement

with dry, fixed-out diffuse D-Log exposure curves.

2.) Repeatibility. Most data has been replicated three

times to demonstrate the repeatability of the IR den

sitometer. This data has been tabulated for ease of

viewing (see tables 1,2, and 3).

Three series of experiments have been run to obtain suf

ficient data for conclusions to be drawn about the above two sta

tements. The two film types used were selected because of their

relatively simple emulsions. It was also desired to run the

experiments with a fairly active developer, and a much milder

developer, hence D-19 and D-76 were selected. Details on how

these experiments were run are listed below.

Series 1 :

Eastman Kodak Fine Grain Release Positive, type 5302,

was processed in D-19 at70*

F for 5 minutes. Sensitometery con

sisted of film samples being exposed in a Kodak model 101 sen-

sitometer. A Kodak #5 step tablet was used along with a 1.20

Inconel N.D. filter. The sensitometer provided 340 lux-seconds

at the wedge. Three runs were made with fresh developer and

rinse water. To prevent contamination of the Fluid Transport

System, no other chemistry was introduced into the system. Scans

30

were taken once per second for the first minute, then once every

10 seconds for the remaining 4 minutes. No scans were taken

during the one minute water rinse that followed development.

All processing was done under Kodak 1A safelight

conditions. After the water wash, film samples were tray-fixed

for five minutes then washed for twenty minutes and dried.

Results from the first run of this series are shown in

figure 8. Wet, un-fixed IR density is plotted as a function of

step # (actual Log exposure values can be found at the end of

this section) . Curves obtained after 30 seconds, 2 minutes and 5

minutes of processing are shown, with the 5 minute curve being

the last one obtained before the water wash.

The curves show just about what one would expect for

this type of developer/film combination. After about 2 minutes

of development, there is no further increase in gamma. At about

the same time, toe densities, as well as the over-all sample

density, begin to pick-up dramatically. For this sample as with

all the others, the IR densitometer would report an initial den

sity of approximately .18 a few seconds after developer contact.

This increase in density is due to the fact that the specular

optical density of AgBr microcrystals embedded in gelatin is

strongly dependent on the water content of the emulsion^. Also,

the optical density does not depend directly on the thickness of

the gelatin, but rather on its index of refraction. As water is

absorbed by the emulsion, the index of refraction will increase,

causing an increase in scattering and therefore, and overall

increase in density will be observed.

Figure 1 1 shows unfixed, wet IR density plotted against

fixed-out dry visual diffuse density. All dry density readings

are made on a Macbeth TD-504 digital densitometer- Some of the

data points are rather far apart because of the high contrast for

this process, but the linearity between the two types of den

sities is clearly shown.

The last graph for this series, figure 14, shows both

wet and dry D-Log exposure curves for a single film sample after

5 minutes of development. Agreement between the two curves is

good with the largest error occurring in the base plus fog por

tion of the curves. Whenever wet IR density and dry diffuse den

sity are plotted together like this, the wet IR density will

always be somewhat higher in the toe region. This again is pro

bably due to the increase in scattering from water absorption

combined with the fact that the device is calibrated with a dry

film base sample (refer to the Software Calibration section con

tained in the operating manual for details). Another intresting

point is that the two curves cross one another close to a density

of .70. This is the density of the mid-point calibration sample

used at the start of the process. At and around densities of

70, the calibration routine used by the IR densitometer forces

differences nearly to zero.

Series 2:

Eastman Kodak Fine Grain Release Positive, type 5302,

was processed in D-76 at70*

F for 5 minutes. Sensitometery con

sisted of film samples being exposed in a Kodak model 101 sen-

sitometer. A Kodak #5 step tablet was used along with a 0.78

Inconel N.D. filter- The sensitometer provided 340 lux-seconds

at the wedge. Three runs were made with fresh developer and

rinse water- Scans were taken once per second for the first

minute, then once every 10 seconds for the remaining 4 minutes.

No scans were taken during the one minute rinse that followed

development.

All processing was done under Kodak 1A safelight

conditions. After the water wash, film samples were tray-fixed

35

for five minutes then washed for twenty minutes and dried.

Results from the first run of this second series are

shown in figure 9- Wet, un-fixed IR density is plotted as a

function of step # (actual Log exposure values can be found at

the end of this section). Curves after 30 seconds, 1 minute 30

seconds, and 5 minutes of processing are shown, with the 5

minute curve being the last one obtained before the water

wash.

The IR densitometer reported an initial density of

approximately .18 due to the usual emulsion swelling from deve

loper absorption. This is not considered to be significantly

different from what was observed in series 1 where D-19 was used.

These curves appear typical, but once again something unusual is

happening in the toe region. The curves show a decrease in base

plus fog density with increased development time. This decrease

in toe densities is probably due to the slight fixation of the

film sample by the developer- D-76 has a relatively high sulfite

content (100 g/1)^, and sulfite is a well-known silver-halide

solvent.

Figure 1 2 shows un-fixed, wet IR density plotted against

fixed-out dry diffuse density- These data were obtained after

five minutes of development, which is always the last scan taken.

More data points are present in this plot because the contrast

for this process was lower. There also seems to be a slight S-

shape to this plot, but a straight line fit still works well if

errors less than +/- .03 D are acceptable. Straight lines have

been fitted to the three graphs of this type. If the plot is

extended, it will intercept the x-axis at approximately .1 dry

diffuse density units. The reason for this probably lies with

the calibration routine used, and the fact that zero density is

derived from a dry film sample.

The last graph for this series, figure 15, shows both

wet and dry D-Log exposure curves for the same film sample after

5 minutes of development. This time the curves cross around .80,

but the reason is still probably due to the calibration routine.

For the toe region of the curve, the comments made about figure

14 apply here also.

Series 3:

Eastman Kodak Commercial Film, type 6127, was processed

in D-76 at70*

F for five minutes. Sensitometry consisted of

film samples being exposed in a Kodak model 101 sensitometer . A

Kodak #5 step tablet was used along with a 1.20 Inconel N.D.

filter- The sensitometer provided 340 lux-seconds at the wedge.

Three runs were made with fresh developer and rinse. Scans were

programmed just as they were in the first two series. Darkroom

conditions and fixing procedures were the same as used in the

first two series.

Results from the first run of this third series are

shown in figure 10. Wet, un-fixed IR density is plotted as a

function of step number (actual Log exposure values for each step

number can be found at the end of this section). Curves after 50

seconds, 2 minutes, and 5 minutes of processing are shown, with

the 5 minute curve being the last one obtained before the water

wash.

The IR densitometer reported an initial density of

approximately .19 due to the usual absorption of developer. This

"wet emulsiondensity"

was noted to be just about the same for

all three series run. The amount of time after the start of pro

cessing it took to reach this density was about the same for all

three series also (5 to 9 seconds) -

The curves in figure 10 show very little increase or

40

decrease in base plus fog density with increased development

time. It might help to explain this by breaking the development

of the toe region into two competing processes. The first pro

cess is the reduction of silver-halide to silver metal. This, of

course, produces density, and may be brought about by the deve

lopment of latent image centers, or the random development of

silver halide crystals to produce fog. The second process is the

slight fixation of the film by the high sulfite developer. This

would cause a reduction in density as the effect of scattering

would decrease.

For the film/developer combinations considered here,

these two competing processes have various outcomes. The first

was Fine Grain Release Positive developed in D-19 Toe densities

increased with time because D-19 is an active developer and fog

production outweighed fixation. The second combination was Fine

Grain Release Positive in D-76. D-76 is a milder developer than

D-19 and fixation proceeded faster than fog and an overall

decrease in toe densities was observed. The last combination was

Commercial Film developed in D-76. Toe densities were noted to

remain relatively constant for this series. A probable reason is

Commercial Film is coarse grained compared to Fine Grain Release

Positive and has almost twice as much silver^. Perhaps this

extra amount of silver halide (coated in two coats), along with

the use of the milder D-76 produced a stalemate between the two

processes described above. That is, perhaps the rate of density

decrease due to fixation was equalled by the rate of increase of

density by fog production and therefore little or no net change

in toe density resulted.

Figure 1 3 shows un-fixed, wet IR density plotted against

fixed-out, dry diffuse density. Again a straight line can be

fit to the data, but the s-shape is more pronounced in this plot

than any of the others. It is felt that a linear model is still a

good choice to describe the relationship, but further study is

41

indicated. It is interesting to note that this same type of S-

o.

shaped relationship appeared in early studies by M.Piskacek0

in

1976.

The last graph of this series ,figure 1 6 , shows both wet

and dry D Log exposure curves for the same film sample after 5

minutes of development. The slopes of the two curves are roughly

parallel and therefore differ mostly by some additive constant.

This constant is probably due to the base plus fog density

remaining almost constant through out the process as was

explained earlier. This is only supposition, and further study

is indicated.

Repeatability Study:

From each of the three different film/developer com

binations, three sets, or replications, were obtained. Recall

from the scan programming used, 100 scans were made during each

process run. As there were 3 replications of each of the 3

series, this makes for a total of 900 scans being taken! Of the

100 scans taken for each process, 8 were selected as being repre-

senative, and are listed as raw data in the appendix (for a total

of 72 scans for all 3 series). To be able to make statements

about the repeatability of the device, the 8 scans recorded were

taken at the same time within each process. Of these 8 scans

taken, 3 from each process run are used in the following analy

sis. The three elasped times selected correspond to the ones used

for plotting the family of curves shown in figs. 8, 9, and

10.

Table 1 is data from series 1. The data are grouped as

to when during development they were acquired. The first column

on the left is the step number. As the step numbers increase, so

does the amount of exposure that particular step received, and

hence an increase in density is noted. The next three columns

are the replicated data sets for the development time under

study. The next D gives the average density of each step for all

three replicates, followed by the sample standard deviation, Sp,

for each step. The last column is simply Dmax-

Dmin for the

three readings taken at each step just to give some idea of what

the data spread is. Table 2 is for data taken during series 2

and table 3 is for data taken during series 3

Tables 4 and 5 show data taken from a fourth run not men

tioned earlier. This data was taken as a fourth replicate of

experimental series 1 and 2, but with one major difference; these

samples were processed without a fresh change of developer -

Also, the tubes leading to the development chamber were not given

46

a chance to drain, as had been the case between all other process

runs. The purpose of this is to demonstrate what effect on data

repeatability using developer warmed by an earlier process run

can have. It was noted that after a process run, the developer

temperature would be 2 or 3 degrees higher that at the start of

processing. Therefore, an increase in density due to an increase

in temperature can be expected. The data in these two tables

support this statement. Average density, D, and the sample stan

dard deviation, Sp, are included to show that the increase is a

real one and not simple variability within the process.

Uniformity of Development:

The Fluid Transport System (FTS), which includes the

chamber, pump, tubing and valves, presented some of the most

complex design problems encountered in the project. The most

important question was; would the flow of developer through the

development chamber give uniform development, or would there be

some type of directional effect. The problem is really one of

hydraulics, and therefore, design procedures are not always as

straightforward as one would like. The main design criterion

was to produce a laminar flow of fluid through the chamber.

Laminar flow is the smooth, uniform movement of fluid that is

free of turbulence and bubbles.

To determine what level of development uniformity could

be obtained once the FTS was actually constructed, the following

experiment was performed.

1.) Samples of Eastman Kodak Pan-X Recording Film, Type

SO-164, were given two levels of uniform exposure. The

first set were exposed to room lighting for five minu

tes to give a developed density of 2.4. The second set

received their exposure from an open-gated Durst

enlarger- The level of exposure was enough to produce a

developed density of approximately 1.5.

2.) All samples were developed in D-76 at68*

F for 5

minutes . Development was followed by a one minute rinse ,

then by a two minute fix. Samples were then washed and

dried in the normal manner.

3.) The pump used by this system has 7 different speed

settings (see Figure 20 for flowrate characteristics) .

This is about the only variable over which the user of

the IR densitometer has control when it comes to flow

56

studies. Therefore, the uniformly exposed samples from

above were each developed at a different flowrate.

The results of this experiment are shown in figures 17

and 18. Figure 17 shows dry, fixed-out diffuse density as a

function of position for the sample that received the room light

exposure. The position marked"IN" is where the developer first

enters the chamber and strikes the film sample. The first den

sity reading is taken there. The next four readings are taken at

equally spaced intervals along the detector region, i.e. the

region of the sample where the eleven IR densitometers are

located. The last reading called"OUT" is from the area just

below the chamber exit port. Figure 18 showns the same type of

graph, but for the samples exposed for a developed density of

approximately 1.5.

The data presented here is not exhaustive, but general

statements about uniformity of development can be made. The data

suggest that as the flowrate of developer is increased through

the chamber, directional effects begin to decrease. However,

this same increase in developer flowrate also causes an increase

in the overall density of the film sample. This all sounds

reasonable as one would expect an increase in developer flow to

bring in fresh developer faster and remove development by

products that could retard development. Another general effect

is that densities always are somewhat higher where the developer

enters and somewhat lower where it exits. This is really not of

much concern as the graphs tell us that if the pump flowrate is

made high enough, very uniform development down the length of the

film where the eleven densitometers read can be obtained. Also,

figure 18 seems to show that even better uniformity can be

achieved as the overall exposure level is reduced. This again

sounds reasonable because as the exposure level is decreased, one

would expect the amount of developer by-products to decrease and

therefore directional effects should lessen.

57

Lastly, if uniformity is critical, users may wish to perform

more exacting uniformity experiments for their particular

film/developer combination. They could then possibly generate a

methodology for correcting their raw data for directional

effects.

Experimental Conclusions and Recommendations:

As should be obvious by now, the amount of additional

research that could be performed on the IR densitometer is tre

mendous. However, it is felt that enough data has been collected

to allow some generalized statements about it's performance to be

made.

First, the assumption that an approximately linear rela

tionship exists between wet, un-fixed IR density and dry, fixed-

out diffuse density seems reasonable. More study is indicated in

this area, with particular focus on what is happening optically

to a wet, developing emulsion. Perhaps experiments should be

conducted with software calibrations being performed when film

samples are wet instead of dry, as is now currently recommended.

Also, all experiments were performed with the anti-halation

backing untouched. Although the backside of the film is never

wetted during processing, perhaps the infrared radiation has some

effect on the backing that could degrade density readings later

on in the process.

Second, the run-to-run repeatability of the device is

considered to be very good. The data from tables 1,2, and 3

seem to indicate that the best repeatability is obtained at lower

densities. As an example, the device is able to hold an average

repeatability of +/- .02 out to a density of .50 for all three

series, or a variability of approximately 5%> This value becomes

only+/-

.03 out to a density of 2.5. Also observed, was that

the more active the developer, the poorer the run-to-run repeata

bility. Other important results from the experiments are the

effect on repeatability due to developer temperature variations .

It was noted that a five minute development run would raise the

temperature of the developer by 2 or 3 degrees. This is due to

the heat generated by the pump and valves, and general frictional

effects. This rise in temperature is enough to cause a

61

significant increase in density if another process run is made

using the same tank of developer. Also, if the tubes leading to

the development chamber are not drained between runs, repeatable

results are difficult to obtain due to solution carry overs. The

full extent of what solution carry over will do, however, is not

known and further study is indicated.

Lastly, uniformity of development across the region

where the IR densitometers are located seems to be very good and

not a source of great concern. There are major directional

effects near the edges of the film sample where the O-ring seal

is located, but these areas are not seen by the IR densitometers.

As was stated earlier, if extreme precision is required, specific

studies can be made to better characterize what little non-

uniformity there is, and correction procedures can be imple

mented. Suggested improvements might be a temperature control

for the FTS and a pump of higher and more consistent flowrate.

In-process IR Densitometer Operating Instructions:

For best results, the user of this device should have a

complete understanding of its operating principles. Not only

does this involve just knowing how to make the device run, but

also a thorough knowledge of how the densitometer works.

This operations manual has been broken up into six main

function groups. They are:

A.) Emitter calibration.

B.) Software calibration.

C.) Film sample preparation.

D. ) Data entry.

E.) Fluid Transport System (FTS).

F.) Prompt descriptions, and error messages.

G.) Printer Maintenance.

The user should read and understand these instructions and

descriptions before attempting to use the densitometer- In this

way, the user can be assured the best possible results, and wear

and tear on the device can be minimized.

64

Equipment List:

Below are listed the various components needed to operate

the In-process IR Densitometer. Some items are kept with the

densitometer and will be found on the lower shelf of the rolling

service cart. Other items are of general purpose and will have

to be located before operating the device.

Items to be kept with the densitometer:

1. Special two-hole registration punch.

2. Modified head for the Kodak Model 101 sensitometer.

3. Calibration samples.

4. Chamber locking pin.

User supplied items:

1. Voltmeter. Range of 20 volts with accuracy of +/- .02 volt.

2. BNC-to-banana-jack adaptor, or some type of adaptor to fit a

female BNC connector to voltmeter being used.

3. Test lead. A clip lead of some sort is neccessay to effect a

ground connection between the voltmeter and the chamber

support frame.

4. Small screwdriver-

5. Darkroom. The densitometer must be loaded and used in total

darkness.

6. Source of fresh water to clean the device when processing is

completed.

65

Procedural Descriptions:

A. ) Emitter Calibration

This densitometer system uses gallium arsenide infrared

emitting diodes (IREDs) as its primary source of radiation for the

measurment of optical transmission, hereafter referred to as

"density". As these sources are diodes, their output intensity

is a function of the forward current passing through the device,

rather than the voltage across the diode.

Two other important considerations must be pointed out

before detailing the calibration procedure. The first is the

type of detector used with the above emitters. Due to their

mode of operation, they can only detect a little more than a

three decade change in light with an acceptable signal to noise

ratio. The second consideration is the operating principle of

the entire IR densitometer itself: the densitometer is to

measure density of a piece of film as it develops. This implies

that the film sample may still have an anti -halation backing on

it while readings are being made. So not only will the density

of the developing silver be measured, the infrared density of the

wet anti-halation backing will also be measured.

The point to all of this is that the user would like to

minimize the effect of the anti-halation backing on the density

measurments. At the same time, the user would also like to maxi

mize the dynamic range of the densitometer to allow for density

readings of at least 3.00 and still maintain some level of

accuracy. Therefore, it is necessary to adjust the output of the

IR emitters to compensate for the various types of anti-halation

backings likely to be processed by this device.

This is done by placing a sample of the particular film

under study, dry and unexposed, into the optical path of each of

66

the eleven emitter/detector pairs. The current passing through

each IR diode is then adjusted until the output voltage of the

companion detector just begins to saturate. Saturation means

the maximum output voltage the device is capable of producing

while remaining linear. The exact procedure is outlined below,

but in this way each emitter/detector pair is optimized for maxi

mum dynamic range in density.

It should be noted that this method of emitter calibration

defines what will be considered zero density. That is, a dry,

unexposed piece of raw film stock will have, by definition, zero

density. All density measurments are therefore relative to dry

unexposed film. However, note that once a film sample becomes

wet, it's IR density will increase due to emulsion swelling.

Procedure:

a). With the main power switch in the off position, discon

nect the Analog Transmission Signal cable from the back

of the control cabinet. This is the black coaxial cable

with the large female BNC connector on the end. The

control cabinet is throughly labeled and will direct

the user to this connector-

b. ) This part of the calibration can be performed with just

about any type of voltmeter- At the time of this

writing, however, aHewlett-Packard digital voltmeter,

(H/P DVM) was available, and thus the procedure will be

detailed for this particular type of voltmeter.

Insert the banana-plug-to-BNC adaptor into the

H/P DVM. The adaptor should be orientated such that the

banana plug marked"COM" fits into the red ground

socket on the front panel of the voltmeter- The other

plug fits into the red socket marked "VOLTS". DO NOT

INSERT BACKWARDS! ! To do so will ground the output of

67

the analog multiplexer and destroy it.

c). Connect the Analog Transmission Signal cable to the

other side of the BNC-to-banana adaptor. Insert a

banana jack test lead into the side of the adaptor

marked "COM". Attach the other end to the metal chamber

support structure. In this way, an electrial ground

path is established between the voltmeter and

densitometer.

d). Select the D.C. volts button on the front panel of the

DVM. Select the 20 volt range button. Turn the DVM on.

Now turn on the main power to the IR densitometer and

wait 10 minutes for it to warm up. The DVM should now

be reading +15 volts +/- .1. This is a test voltage

upon initial power-up. The output of these detectors is

directly proportional to the amount of incident flux

striking them, therefore, the output is considered a

transmission signal.

e). In complete darkness, or under safelight conditions if

the film will allow, punch a set of registration holes

in a sample of the film type under study. Cut it long

enough to cover all eleven detectors, about 8 inches.

This is then mounted in the chamber, placing the strip

such that the registration holes fit over the two pins

at the rear of the chamber. It is most important that

the film be mounted emulsion side up, toward the deve

loper channel. Lastly, close the chamber and seal it

with the locking pin. The device is now ready to be

calibrated.

f). When the main power was first applied, the system came

up and prompted: "EMITTER CAL?". If the user is going

to process a film type different from that for which the

device was last calibrated, an emitter calibration will

be necessary. To select the calibrate mode, enter any

number from 1-9 , followed by an"E"

depression. The

system will respond with the prompt: "EMITTER 1". This

68

means that the emitter/detector pair at the top of the

chamber (#1) has been activated.

g) . The DVM should now be reading some voltage. Adjust the

grey trimpot marked #1 located behind the chamber with a

small screwdriver until the meter reads approximately

13-0 volts +/-.2 volt. Turn the pot clockwise to

increase the voltage. Turn it counter clockwise to

decrease the voltage.

h). Press the "E"

key and the display will change to:

"EMITTER 2". Repeat as above for all eleven emitters.

When complete, the system will again prompt: "EMITTER

CAL?". To leave this calibration mode, enter zero,

followed by "E". This will jump the user to the next

prompt.

i) . When all eleven emitters have been calibrated, turn the

machine off and reconnect theAnalogTransmissionSignal

cable to the control cabinet. Remove the film base

sample from the chamber and continue with the software

calibration routines.

Note that this emitter calibration will be valid as long

as the same type of film is to be used. Turning off the power

will not change the settings of the trim pots, therefore, this

calibration does not have to be performed each time the device is

powered up. The only time the emitters have to be calibrated is

when processing a film type different from that for which the

device was last calibrated.

69

B. ) Software Calibration:

The basic premise behind the software calibration is that

the relationship between wet unfixed IR density and dry, fixed-

out diffuse density is a linear one. This important fact was

amply demonstrated by M. Piskacek in 1977.

The operation of the software calibration is very straight

forward. Certain conditions are established within the develop

ment chamber, (detailed below) and a single complete density scan

is made. The eleven readings that result are considered to be

zero density, and stored in memory as MDO (measured zero

density). New conditions are again established within the

chamber, this time with a film sample of uniform density large

enough to cover all eleven emitter/detector pairs. The density

of this sample should be near the mid-point of the maximun den

sity the user expects from the particular film/developer com

bination under study- For example, if a maximum density of 2.00

is expected, the calibration standard would have a density of

1 .00. The density of this sample is known, and entered into the

computer as ADMAX (actual maximum density). ADMAX is only a com

puter variable name, and really refers to mid-range densities.

Another complete scan is made and a new set of eleven readings

result. These are stored in memory as MDMAX (measured maximum

density). With this information now in memory, the computer can

now perform eleven seperate linear regressions and generate ele

ven unique slopes and intercepts for each of the eleven

emitter/detector pairs. In this way, as raw data is generated,

it is operated on by a first order calibration routine. The

final densities viewed later by the user, will have been

corrected from wet, IR density to equivalent dry, diffuse den

ADMAX = Actual maximum density.

MDO = Measured zero density.

Rcall that eleven slope and intercept pairs must be

generated for all eleven emitter/detector pairs.

From the plot:

MD = (AD) x (SLOPE) + INTERCEPT

and the intercept is simply:

INTERCEPT = MDO

From another point on the plot:

MDMAX = (ADMAX) x (SLOPE) + MDO

72

Solving for the slope:

SLOPE = (MDMAX - MDO) / ADMAX

Lastly, corrected densities can be calculated from:

AD = (MD - MDO) x ( ADMAX / (MDMAX - MDO) )

Software Calibration Procedure:

a). This calibration is to be performed after the emitter

calibration. If the same type of film base is to be run

for this processing session, and no emitter calibration

was performed , turn the machine on and allow a 1 0 minute

warm-up before proceeding.

b) Open the chamber door- Make sure the chamber is abso-

lutly clean and dry. Any moisture in the chamber will

have an adverse effect on the calibration. Insert the

calibration strip into the developer channel. The

calibration sample is any material of uniform,

known, IR density, close to the mid-point of the

expected density range being investigated.

Ideally, it should be cut to fit inside the deve

lopment cavity, up against the IR emitters. It is

important that it be placed in the channel so it

will not affect the closing of the chamber door.

Apply slight pressure to make sure that the strip

is seated firmly in the channel.

c). In total darkness, or under safelight conditions if the

film will allow, unroll about eight inches of the film

under study. Punch two registration holes into one end

of the film strip using the special punch provided.

Mount the film into the development chamber by aligning

the two pins at the rear of the chamber into the holes

73

just punched. Be sure to mount the film emulsion side

up, toward the developer channel. Hold the other end of

film strip flat against the chamber bottom, close the

chamber and seal it with the locking pin.

d.) If the machine has just been turned on, the prompt

"EMITTER CAL?"will be on the display. If performing an

emitter calibration, complete the calibration and

depress the "E"

key until this same prompt appears. To

get to the software calibration mode, enter zero and

depress "E". The system should respond with: "ENTER

D-MAX". The user should now enter the value of the

calibration sample to be used. Remember that the deci

mal point is implied. That is, a density of 1.20 is

entered as 120. After entering D-max, depress"E"

. The

next prompt will be: "READ D-MAX". The next depression

of the "E"

key will read the density of the calibration

sample plus the density of the dry film base. The value

of this reading is assigned the calibration values just

entered by the user.

e). The system will now be prompting: "READ ZERO". Open the

chamber and carefully remove the calibration sample.

Try not to disturb the film sample while doing this.

Reseal the chamber door and press the"E"

key. The

system has now just read the density of the film sample

and assigned it the value of zero density.

f). Open the chamber and remove the film base sample.

The prompt: "ENTER MONTH"should now be on the display.

At this point, the device is 100% calibrated and ready

to go.

74

C. ) Film Sample Preparation:

This device was originally designed to measured the den

sity of a film sample that had been exposed to a standard 21-step

sensitometric tablet. Alignment proved difficult, however, so a

Kodak #5 step tablet is to be used for making all sensi expo

sures. This tablet has a step increment of about .30 density

units, and has been mounted in a standard Kodak 101 sensitometer

head. Note that any step tablet can be used, just as long as the

step spacing is exactly 10.00 mm, otherwise poor registration of

the step exposure to the detectors will give poor results.

Before making any exposures, make sure that this sen

sitometer head has been obtained! The procedure for making

sensitometric exposures is as follow:

a). In complete darkness, unroll about eight inches of the

film under study. Use a safelight if the film will

allow. Cut the film as close as possible to a right

angle with the edge of the film. Punch two registration

holes into the film with the punch provided.

b). Align the holes in the film to the pins mounted on the

end of the sensitometer head. Mount the film on the

head with the emulsion facing the light source. Make

the exposure. As with all sensitometer work, the best

filter combination will have to be determined by calcu

lation or trial.

c). Mount the exposed sample in the development chamber.

The emulsion side always faces up (toward the emitters) .

Close the chamber and seal it with the locking pin. The

film sample is now ready for processing. Remember that

the room lights have to remain off while the film is

being loaded and processed.

d.) The correct response to the "ENTER MONTH"prompt is to

enter the two digit month code followed by an"E"

75

depression. This is repeated for the "ENTER DAY"and

"ENTER YEAR"prompts.

e.) The prompt: "MANUAL MODE?"should now be on the display.

To select manual mode, enter any number from one to ten

followed by an"E" depression. The printer will respond

with the heading: "*** MANUAL MODE SELECTED ***". To

select automatic, enter zero then a"E" depression. A

more detailed description of manual mode and automatic

is contained in Section E: Fluid Transport System.

76

D. ) Data Entry:

Other than calibration, the user must also program the IR

densitometer with certain process information. The device must

be told for how long it is to process film samples and when to

take density scans. This is done in the following manner:

a) - During the programming stage, the user will receive the

prompt: "PROCESS 1=?". The device is asking the user

how long to run the first process. There are three

tanks and therefore the machine is capable of running

three processes. This prompt is answered by entering

any number in the range of 0 to 127 minutes. The

smallest increment of time is one minute. Invalid

entries are flagged as errors (see error message table) .

b) . As this system has the ability to generate an incredible

amount of data, a very selective methodology for the

programming of scan acquistion was needed. This was

accomplished by breaking each process into a number of

smaller intervals. Then for each interval, a rate at

which scan data will be acquired is defined. This rate

is expressed as the number of scans to be taken per

minute, with the range being from 1 scan/minute to 60

scans/minute. It is important to note that the system

defines scan rates on a minute by minute basis. This

means that for an entered scan rate of 32 scans/minute,

the system will round this down to 30 scans/minute and

take a scan every 60 / 30 = 2 seconds. This was done

because the shortest time for which a scan rate can be

defined is one minute.

c). After entering the process length, the system will

prompt for the interval length. If an interval length

of zero is entered, the device will assume that the user

wishes to make no scans during this process and therefore

jumps the user to the next process length entry. If

77

scans are to be made, the user should enter an interval

length over which data is desired. At all times it

should be remembered that the system can store only 187

scans and great care should be exercised not to exceed

this value. Also, the entered interval cannot be

greater than the process length. Once the interval

length has been entered, a scan rate must be entered.

The number of scans generated during any interval is

simply the interval length times the scan rate. If

invalid interval or rate information is entered, error

messages will be issued.

d). Interval/rate data can be entered until:

1.) The number of generated scans equals 187.

2.) Ten interval/rate pairs have been entered.

3.) The sum of the interval lengths equals the pro

cess length.

4.) An interval length of zero minutes is entered.

e). This procedure is repeated for each of the three pro

cesses. If manual mode has been selected, the user is

allowed to program only one process as the FTS is under

total user control.

Every effort has been made to design the most efficient

user interactive operating sysem as possible. There are,

however, some ways a user can get into trouble. The most common

mistake to be made is to use up all scans before the process is

finished. This is done by entering an interval/rate combination

that generates many scans. As an example, an interval length of

3 minutes and a rate of 60 scans per minute will produce 180

scans. This does not leave many scans for anything else.

Remember that there are a total of 1 87 scans available and not

187 scans for each process. Once interval/rate information has

been programmed, there is no way to clear it and start all over

again. Either the device must be turned off and re-started or

the programmed data has to be run through. The point is, be

78

careful when programming scan data!

At the completion of processing, the system will return

control to the user with the prompt: "PROCESS # =?"

. Please refer

to the prompt descriptions contained in Section F for directions.

79

E.) Fluid Transport System (FTS):

The Fluid Transport System, or FTS for short, consists of

any component having to do with the transportation of chemistry

to and from the development chamber- This system has two modes

of operation, automatic and manual. There are certain aspects of

this system that require earful attention, and will be repeated

through-out this section. The first and formost is; never run

the device with the processing tanks empty! To do so will cause

excessive wear of the pump gears and shorten pump life.

Considerations of the two modes of operations are listed

below.

Automatic:

During the programming of the device, the user will

receive the prompt: "MANUAL MODE?". To by-pass manual mode and

select automatic, the user must enter a zero followed by an"E"

depression. Once in automatic mode, the computer will handle the

complete operation of the inlet and outlet valves, and the pump.

What is not under computer control, however, is the speed of the

pump and the detection of fluids within the tanks. These two

areas are always the user's responsibility.

To set the pump speed, locate the small knob mounted top

dead center over the pump housing. The pump itself is located

just below the chamber and right above the chemistry tanks. Refer

to figure 20 for flowrate details. Position "0" is off. Position

"8" is maximum speed. Best results are obtained at position "7",

but the speed selected is up to the user. Tanks should be filled

to just below the mounting screws, (about 2 liters) with care

being taken to avoid spills onto the control valves. When

programming for process lengths while in the automatic mode,

the user can run each tank for 127 minutes each. Any combination

of tanks can be run, but no tank can be run more than once, and

81

the order of usage is always tank 1, tank 2, tank 3. When the

system begins to process, it has no way of knowing if the door

to the development chamber is open or not and will always assume

that it is closed. There is, however, an interlock switch on the

chamber to interrupt the A.C. power to the pump if the door is

left open, but the computer does not know this and will always

try to start the pump. Even if the door is open, the inlet and

outlet valves will open and the programmed timing sequence will

begin. To see what exactly is turned on, refer to the FTS relay

control box mounted under the cart and to the right. There are

three pairs of LEDs and a single red LED at the bottom. The two

leftmost red LED pairs are the contol indicators for tank 1

inlet and outlet valves. The center two pairs are for tank 2 and

the two on the right are for tank 3. The red LED by itself on

the bottom is for the pump. Note that the layout of these LEDs

is duplicated on the front panel of the control cabinet. This

will be detailed below.

Manual:

To select manual mode, answer the "MANUAL MODE?"prompt by

entering any number from 1 to 9 and depress the"E" key- The

printer will print** MANUAL MODE SELECTED ** and the manual FTS

control buttons on the front panel of the control cabinet become

active. When in manual mode, it is the user's responsibilty to

control the switching of tanks and the operation of the pump.

This is to allow for the user to switch between any tank as often

as desired. Tanks can be mixed, drained, new chemistry can be

added, etc. The main purpose is to allow the user complete ver

satility in the processing of film samples.

Another reason for this manual control is for the draining

and cleaning of tanks when finished with the device. To drain a

tank, the procedure is as follows:

82

a.) Locate the manual drain valve. It is the extra

length of tubing that extends out from the top

row of valves. Open the valve and place the free end

of the tubing into a suitable container. See figure

21 for a schematic diagram of this system.

b.) Depress one of the tank outlet buttons on the front

panel. The valve should open with a loud snap. No

more than one tank out button should be on at a time.

If the manual drain valve is open, do not open any of

the tank inlet valves, otherwise the tank will take

forever to drain. Now that the bottom of a tank is

open, depress the PUMP ON switch. Remember that the

pump will only go on if the chamber door is sealed.

Also, always keep a piece of film in the chamber when

draining tanks, as this makes a better seal in the

chamber and it is less likely to leak.

c.) The tank should now be draining through the drain

valve. Listen carfully for a sudden increase in pump

speed. This is the best indication of when the tank

is empty. Quickly turn off the pump, then the tank

out valve. Repeat for any other tanks that need

draining.

Important Note: NEVER NEVER! ! try to operate the pump without

having at least one outlet valve open and one inlet valve open.

The drain valve can take the place of a inlet valve, however.

The point is that the pump must always have a souce from which to

draw fluid and someplace to put the fluid. The pump can be

damaged if made to draw from sealed tanks or empty tanks. Also,

hoses may burst if the pump is not given an outlet destination.

Therefore, ALWAYS make sure that the proper valves are open

before turning on the pump. It is very easy to make this mistake

so, BE CAREFUL! ! !

Tank Cleaning:

The best method for cleaning the tanks is also the

eaisest. Place the device into manual mode. Fill all three

tanks with clean, lukewarm water- Set the pump speed to about

"5". Load a clean film sample in the development chamber.

Open tank 1 inlet valve and outlet valve. Start the pump and run

it for about 30 seconds. Now open the drain valve and close tank

1 inlet valve. The tank should now drain. Repeat this for the

remaining two tanks. Remember that when the pump speed begins to

increase, the tank is empty and the pump must be turned off imme

diately.

85

F. ) Prompt Descriptions and Error Messages

This section gives a brief description of every prompt

the user will encounter when operating the In-process IR den

sitometer- The prompts are listed in their order of appearance

to help guide the user through all steps of device usage.

Prompt User Action

"EMITTER CAL?"

"ENTER D-MAX"

"READD-MAX"

"READZERO"

"ENTERMONTH"

Device wishes to know if user would like to

perform a hardware emitter output calibra

tion. See calibration section for details.

To perform the calibration, enter any number,

then press "E". System will respond with

"EMITTER 1 ,2,3- - -

" for each"E" depression.

Eleven depressions return the user to

orignal prompt. To exit , or skip calibration,

enter zero and press"E"

.

Enter the density value for the sample used as

calibration standard. See calibration sec

tion for details . Density values are entered

to the nearest hundredth with the decimal

point implied. Example; 1.20 is entered as

120. Press"E"

after entering correct value.

This is the prompt for the actual reading of

the calibration standard. Place film stock

sample and calibration strip into chamber and

seal. Press"E" to take reading.

Remove calibration strip from chamber, but

leave film stock sample. Seal chamber door and

press"E" to take zero reading. See calibra

tion section for complete explantion of

calibration routine.

System is prompting for information so it can

print a date header- Enter two digit month

86

"ENTER DAY"

"ENTER YEAR"

"MANUAL MODE?"

"PROCESS 1=?"

code followed by"E"

depression.

Enter two digit day code, followed by"E"

.

Enter two digit year code, followed by "E".

system will print date header in the format:

xx/yy/zz.

System is asking user if manual or automatic

control of the FluidTransport System (FTS) is

desired. Any number entered followed by the

"E"

keywill enable front panelbuttons and put

FTS under manual (user) control. A zero

followed by"E"

willplaceFTSunder automatic

(computer) control. See FTS description for

details. If manual mode is selected, system

will print:** MANUAL MODE SELECTED **.

Enter 1st process length in minutes. Legal

range is zero to 1 27 minutes . Process length

can only be entered in increments of one

minute. See data entry section for details.

After depressing"E"

key, system will print:

Process 1 = xyz minutes.

Note: An entered process length of zero minutes will jump user to

"PR0CESS2 =?"

prompt. However , if manual mode has been selected,

system will display"BEGIN"

query instead and assume no scan data

is to be taken.

"INTERVAL 1=?" Enter interval length in minutes; then press

the"E" key. For the programming of scan

acquisitions, the user must break up the

entered process length into indivdual inter

vals. For each interval, the user must then

enter a scan acquisition rate (see below).

The sum of all the entered intervals cannot

be greater than the total process length. If

the sum is greater, an error prompt is issued.

87

"RATE 1=?"

See error prompts for details.

For the just-entered interval, a scan

acquisition rate must now be entered. Legal

rate entries are 1 scan/minute to 60

scans/minute (these translate to 60 seconds

per scan to 1 second per scan) .The system has

the ability to store 187 complete scans. A

running sum is kept internally as the user

programs intervals and rates. The number of

scans any combination generates is simply the

rate times interval length.

"INTERVAL 2=?"

If an entered rate value, in con

junction with the just entered interval,

generates a scan sum greater than 187, the

system prompts "RATE TOO BIG". If the scan

sum exactly equals 187, the system prompts:

"OUT OF SCANS"and prints out as follows:

Interval 01 = ab minutes

Rate 01 = xy scans/minute

Interval/rate combinations may be entered

until:

1 .) The sum of interval lengths equals

process length.

2.) Scan sum equals 1 87. Note that even

though this is stored internally, it is not

available for user display, and it is there

fore the users resposibilty to keep track of

the scan sum independently of the machine.

3.) Ten interval/rate pairs have been

entered.

Note: Entering an interval length of 00 minutes will jump the

user to the next process. In the case of manual mode, only one

process is allowed.

88

"PROCESS 2=?"

"PROCESS 3=?"

"BEGIN"

Same methodology applies for Process 2 and 3

As an example, if all scans are programmed in

Process 1 and the "OUT OFSCANS"

prompt is

obtained, the remaining processes can still

be run, however no scan acquisition data can

be programmed.

At this point, system is ready to begin pro

cessing. User should now check to see that

tanks are filled, chamber door is sealed, etc.

Processing will begin when enter key is

depressed. If manual mode has been selected,

it is up to the user to operate the manual FTS

controls. Scan acquisition will still be

under computer control, however. If manual

mode has not been selected, the FTS will be

under complete computer control also.

Note: When processing is started, all displays will go blank

(except the digital thermometer). The user can do nothing until

processing is complete. If the processing must be interrupted,

the main power switch is the only way to stop the device.

"PROCESS#=?"

"TIMEWANTED"

When processing is complete, system returns

with this prompt. User is now to enter pro

cess number from which it is desired to view

scan data. Legal entries are 1,2, or 3 only,

followed by "E". If a process number is

entered for which no scan acquisition data has

been programmed, the error prompt "NODATA" is

displayed.

First set of double zeros are the number of

minutes into selected process user wishes to

view data. Legal entry range is 00 to 99

minutes, followed by the "E"key.

89

"TIME WANTED"Second set of zeros are the number of seconds

to be added to the number of minutes already

entered to form total time into process user

wishes to view scan data. Legal entry range

is 00s to 99 seconds, followed by"E"

.

Note: Time entries of 00 min 00 sec are not allowed and will

return user to "PROCESS #=?"prompt.

"TIME ELAPSED" The times at which scans are made depends on

how the scan acquisition data was programmed.

Therefore it is possible for the user to enter

a time at which no scan was made. The system

will locate the closest scan made to the ela

psed time wanted and display this actual scan

time along with the scan data on the density

display.

90

Data View Mode j_

Once the first set of scan data is displayed, the special

function keys become operative. Their functions are outlined

below:

UP: Depressing this key will advance user to next acquired

scan. Density display will show this new information

and prompt display will be updated to show change in

elapsed time. If already showing last scan in process ,

system will display: "NO MORE DATA".

DWN: This key will cause system to display scan acquired

prior to present scan already on display. Note that

time steps between scans are determined by scan rate

information programmed earlier by the user. If very

first scan in process is already being displayed,

pressing"DWN"

will cause system to display: "NO MORE

DATA".

PRT: This key will cause the line printer to generate a copy

of the scan data presently being displayed. The pro

cess number along with the elasped time are also

printed as the header. This key has absolutly no

effect on the display contents.

NXT: Depressing this key will simply return the user to the

prompt: "PROCESS #=?" . In this fashion, desired scans

can be arrived at directly, rather than inched up to

with the UP and DWN keys.

"E"-"E" Two"enter" key-strokes in sucession will return the

user to "MANUALMODE"

query. This is to be done only

when the user has completed the inspection of process

results and wishes to make a new process run. Any

number entered followed by an"E"

will then enable the

FTS manual control. This is to allow the user to

change or alter the contents of the process tanks if so

desired. A zero followed by the"E"

key will jump the

91

user back to the "ENTER MONTH"prompt. An entire new

process run can now be programmed. All calibration

values obtained earlier are retained.

Note: Once the user has entered two"E"

key strokes, there is no

way to return to the data view mode except to run a complete new

process. Also, the double"E"

stroke will only work when the

message: "TIME ELAPSED" is on the prompt display.

92

Error Messages j_

The following error prompts are returned by the system

when the user makes an illegal or invalid keyboard entry. Error

prompts will appear after an"E" depression and remain on the

display for approximately five seconds. After this time, the

system will reprompt the user for the correct entry. For criti

cal errors, the re-prompt will be flashing on and off to alert

the user that some careful thought is required.

Error prompt: Meaning;

"PROCESS FULL"

"RATE TOO BIG"

"OUT OF SCANS"

"NODATA"

"NO MOREDATA"

Not really an error, but just informing the

user that the sum of entered intervals now

equals entered process length, and no more

interval entries will be allowed.

Entered rate in conjunction with just entered

intervalwill generate more scans than system

is capable of storing (187). Solution: re

enter smaller rate.

A reminder to the user that all scans have

been used up. Further interval/rate entries

will not be allowed.

Response to user request for data from a pro

cess where none has been acquired.

Response generated as user views a block of

scan data and comes to the top or bottom of

that data block.

Note: Certain types of invalid entries will generate no error

message. What will happen, however, is that the number field of

the prompt display will be re-set to all zeros, and the prompt

will begin to flash. In this way, the user cannot proceed in

system programming until a legal entry is made.

93

G. ) Printer Maintenance:

There are only two types of service operations the IR den

sitometer user may attempt on the 40-column line printer. They

are to change the ribbon cassette and to install a new roll of

paper. For other problems, it is recommended that the printer

manufacturer be consulted (NCR corporation).

Important note: Always disconnect the A.C. power cord

before attempting to service the printer. A.C. line voltage is

present within the control cabinet and a severe electrical shock

could result from the inadvertent touching of one of these con

nections .

To install a new ribbon cassette:

1 . Remove the old ribbon cassette from the printer. This

is done by gently squeezing the two plastic locking tabs

at the center edges of the cassette together and lifting

the cassette off the printer.

2. Before installing the new cassette, locate the small

white ribbon advace knob on the underside of the

cassette. Slowly turn the knob in the direction indi

cated by the arrow until any slack in the ribbon is

removed. To replace the cassette on the printer, again

squeeze the locking tabs together and set the cassette

back onto it's support tongs.

To install a new roll of paper:

1 . Remove the ribbon cassette from the printer as described

above.

94

2. Lift out the two vent plugs located just behind the

printer on top of the control cabinet.

3. Slide the entire top panel out the back of the cabinet.

Pull the panel out squarely as to prevent it from

jamming. Lift slightly as the front end passes over the

printer mechanism.

4. Step behind the device and view the paper feed spool

located just behind the printer. Remove the wood spool

from it's supports by lifting straight up on it at both

ends .

5. Slide off the two plastic spacers and discard the card

board core from the old roll. Insert the wool spool

into a fresh roll of paper. The curl of the paper

should be facing you. The long plastic spacer goes on

the left and the short one on the right. Replace the

entire assembly by guiding the slots in the spool into

the U-shaped support holes.

6. Important! ! Check now to see that the paper roll rota

tes freely on the spool and that it does not bind. If

the roll is binding, it is because the wood spool was

not replaced squarely in it's supports. Remove and

replace if necessary.

7. While still standing behind the device, locate the feed

roller release lever. This is a white plastic lever on

the right hand side of the printer. Gently pull this

lever towards you and note how the platen lifts away

from the feed roller. While holding the platen open,

feed the end of the paper under the metal roller oppo

site the rubber feed roller. Guide the paper out the

top of the printer until the paper is feeding squarely

95

off the supply roll. Release the lever and tear off the

excess paper you just pulled through.

8. Replace the top panel, again lifting the front edge

slightly as it passes over the printer. Replace the two

vent plugs. Before replacing the ribbon cassette,

remove any slack by turning the white knob that is under

the cassette in the direction indicated.

9. Reconnect the A.C. power-

Appendix J_ j_ Input/Output Port and Peripheral Device Addressing

1 . ) Line Printer Data and Control Lines:

The 40-column line printer is considered to be I/O mapped

I/O. That is to say, all operations with the printer are made

through three I/O ports. Port addresses and bit designations are

listed below. Data is clocked into the printer by the printer

clock input line and the clock signal itself is derived from the

Timer Out pin located on the expansion 8155 (chip A17). The

Printer Reset input is derived from the buffered 8085A Reset Out

signal. See the NCR users manual and the SDK-85 users manual for

more complete details.

All the Input/Output ports listed below have been opti

cally isolated from the peripherals they communicate with. The

devices used are Hewlett-Packard 2731 opto-isolators . For more

details, consult the system schematics in the appendix. The pur

pose of the isolation is prevent noise crossover between the

digital and analog systems.

4. ) 33-Digit Density Display/Keyboard System:

The 33-digit density display system is controlled by the

expansion 8279 keyboard/display controller- This controller has

an internal 16 byte/32 digit display RAM that is written to and

read from by the 8085A CPU. For a more complete understanding on

how the 8279 works, refer to the Intel MCS-85 User's Manual

#9800366E.

Display Section:

The 8279 can be considered as memory mapped I/O. It is

communicated with via the CPU as if it were a simple memory loca

tion. The two addresses of concern are:

Command Address : B801H

Data Address : B800H

Each byte in the display RAM is configured as : BBBBAAAA,

where the four hi-order bits make up the B section and the four

lo-order bits make up the A section. The hardware is set up to

display each section as a BCD digit. Therefore, sixteen bytes of

RAM with two nibbles each give a total of thirty-two digits. The

physical display addresses are shown in the following list. The

top left most digit is hard-wired to always read zero.

(top view).

Keyboard Section:

The 8279 keyboard section is used in the encoded scan mode

with 2-key lock out. When reading the FIFO, keystroke addresses

are mapped as shown below:

104

CFH CBH C7H C3H

CEH CAH C6H C2H Keystroke addresses in

CDH C9H C5H C1H relation to actual key

CCH C8H C4H COH pad location (top view).

5. ) Twelve Character Alphanumeric display:

The twelve character 5x7 dot matrix alphanumeric display

is controlled by the MTX-A1 display controller. The MTX-A1 is

also set up as memory mapped I/O and therefore is treated as a

single memory location. All commands and display data are writ

ten to what is known as the control address.

Control Address : BF00H

The MTX-A1 also contains a 32-character RAM, and is very

similar in operation to the 8279. For complete details of opera

tion, see the MTX-A1 User's Manual.

The relationship between character address and physical

location is shown below:

BA9876543210

The display is written to from right to left and any excess

characters roll off the left end and are lost.

6. ) Five Digit Control Display:

These five display are simply wired in parallel with the

displays mounted on the SDK-85- There is a small eight position

105

DIP switch located on the SDK-85 board that is used to switch

between the two display systems. These displays are controlled

by the Basic 8279 Display Controller. See Chapter Five of the

SDK-85 System Design Kit User's Manual #9800451B for a very

complete description on how these displays are used.

Appendix 2_ j_ Operating System Program Listings :

The most difficult portion of this thesis involved the

development of the operating system control software. This

appendix contains a short description of what each program does,

followed by the complete listing of the assembled programs. The

code is Intel 8080/8085 assembly language. All programs where

developed on an Intel Intellec MDS-220 development system. All

software calculations are performed by routines contained in the

Intel Floating-Point Arithmetic Library (FPAL) . The operations

provided are addition, subtraction, multiplication, division

value comparison, negation, clearing to zero, absolute value,

conversion between decimal and binary floating-point numbers and

conversion between floating-point and 32-bit signed integer for

mats . All operations are 32-bit single-precision ( positive

number range approximates 1.2 x10~38 to 3-4 x

10^8 ). The

32-bit single-precision format is fully described in the

8080/8085 Floating-Point Arithmetic Library user's manual,

available from Intel Corporation, SanataClara, California, order

# 9800452-03-

Control of the IR densitometer is divided between seven

different programs or modules. Each module is developed and

debugged separately from one another. Once all programs are

debugged, they are linked together to form one complete program.

For this system, the linked programs require about 1 OK of program

memory to run.

These program listing are provided to allow qualified

persons to change or up-grade the IR densitometer operating

system when needed. If more information is required, please con

sult the numerous Intel manuals concerning this subject.

109

1 . Module CALIB:

This module performs all the initializations required to

operate the IR densitometer. For example, certain memory loca

tions and registers will contain unknown variables upon first

power up. This program then loads these locations with the

proper contents. This program also contains the sub-routines

that; scan the 11 emitter/detector pairs, manage the output of

data onto the 33-digit display, and perform the data calibration

functions.

2. Module START:

Module START is a warm start routine in that after a pro

cess has been run, certain parameters have to be re-initialized.

START also contains all the routines that control the 40-column

line printer -

3. Module DATAIN:

Thismodule interacts directlywith the densitometer user

to program certain process information. All timing and rate

information is entered through this program and is also checked

for validity. The majority of message tables are stored within

this module, along with all delay routines.

4. Module SUBPAK:

SUBPAK contains all the routines needed to operate the 1 6

pad keyboard. When the user depresses a key, subpak determines

which key has been pressed and loads its address and value (if it

is a numeric key) into a series of memory locations called KSTOR.

From there, it is up to the calling program to determine what to

do next.

1 10

5. Module GODEV:

This program starts by displaying"BEGIN"

on the prompt

display. From there it simply controls the timing of the Fluid

Transport System, and the timing of scan acquistion. GODEV also

contains a memory allocation routine used to store density data

as it is generated by the A/D converter. All timing functions

are based on a 1 Hz clock input to RST 7.5.

6. Module DFIND:

This module is entered when processing is completed. The

user enters a time at which density data was acquired, and the

routine will calculate the memory address at which that data is

stored. A routine to convert minutes to seconds is also con

tained here.

7. Module UPORDN:

Control of the special function keys is defined here.

This program functions very similar to DFIND in that memory

addresses are calculated depending on what density data is

desired. Exit from this program will return the user to START

where a new process run can be made.

Appendix 3j_ Raw Data

The first section of data that appears here is for EK

Commercial Film, type 6127 developed in D-76. The raw data is

reproduced directly from the printer tapes that are output by the

IR densitometer. After this first set was collected, the

electronics that control the printer broke down and the unit had

to be returned to the manufacturer for repair. The remaining

data from the Fine Grain Release Positive experiments was repro

duced by hand from the 33-digit LED density display. The IR den

sitometer will still work without the printer, but it certainly

saves a lot of work for the user.

At the time of this writing, the control electronics

still had not yet been returned from the NCR Corporation.

VITA

Steven Paul Cox was born a U.S. citizen in Los Angeles,

California, in 1955. Raised inBurbank, California, he attended

John Burroughs High School and graduated in 1973. The next five

years were spent as a freelance photographer in the Los Angeles

area, camera salesman, and a photography instructor for the

Burbank Adult School Program. During these five years, he also

obtained his B.S.E.E. from the California State University at

Northridge.

During his last summer in California before coming to

Rochester in 1978, he worked for Rockwell International on the

Clinch River Fast Breeder Reactor project. Finding no joy in

government contracts, he left Los Angeles to pursue his Masters

of Science in Photographic Science and Instrumentation at the

Rochester Institute of Technology. While attending RIT, Mr- Cox

has worked part time for the Itek Corporation in the design of

microprocessor controlled graphic arts cameras. In the spring of

1981, this thesis was presented at the annual SPSE conference in

New York City.

Mr- Cox hopes to some day return to his native

Calif iornia.
