Enclosure (a) Revised Statement of Items of Work of Proposed
Task III "Analysis and Test of Viewing and Mensuration Equipment"
Item 1. Analysis and Test of Existing Viewer
Analyze the design and test the operation of an existing customer
furnished viewer to develop procedures, measuring devices and standards.
The following factors are typical of the aspects to be covered:
(a) Examine film transport for speed, smoothness accuracy
and tracking.
(1) Review soundness of design approach.
(2) Determine suitability of available test films
and procure samples for tests.
(3) Design and procure samples of special test
films where necessary for special tests.
(4) Determine range and least count of test
A
instruments needed.
(5) Make an error analysis of smoothness determination
and where feasible make a power spectrum analysis
of velocity.
(b) Establish a review check list for such items as:
(1) Loading and loading diagrams
(2) Controls and markings
(3) Circuit diagrams
(4) Circuit breakers

High voltage interlocks
Roller alignment and bearing sticking
Personnel safety considerations
(c) Review basic principles of structure design for:
(6)
(7)
Sound geometry
Good joints
Properly sized and braced members
Good structural damping
Adequate well designed doors and access
panels.
Operating vibration levels
Operating sound level
(d) Examine and test illumination and optics for:
(1) Magnification
(2) Distortion
(3) Brightness distribution
(4) Brightness levels
Item 2 "Analysis and Test of Additional ESui ents"
Analyze the, design and test operation of such customer furnished
equipment as is designated from time to time by the Technical
Representative of the Contracting Officer. Effort will be directed
toward establishing procedures, instructions, and specifying test
equipment on first article tests so that customer or contractor
technicians can readily test following production items.

(d) Establishment of standardized design criteria
for basic common components to promote inter-
changeability rigidity and reliability.
(e) Air platen of low noise and high stability.
(f) More widespread application of liquid gate or
liquid bath film cleaner.
Item 4 "Structure An~al~ysis and)lib_x_wt o, Control"

Item 5 "Viewer Illumination Standards"
(a) Review standards and formulate procedures for test and
for aiding in improvement of precision of specifications.
(b) Review illumination measuring equipment for usage, range
and least count and evaluate applicability to viewing and mensuration
equipment.
(c) Review the design procedures and performance criteria
for lamp, condenser and projection lens for potential improvement
in performance.
Item 6 "Computer/Viewer Augmentation"
Explore the feasibility of augmenting the role of the computer in
relation to the projection viewer as an aid to the interpreter.
. (a) Review availability and application of small special
purpose computers to viewing and mensuration equipment with
particular regard to economics and simplified programming.
Item 7 "Film Distortion and Format Temperature Study"
)(a) Heat Balance Analysis: Make literature search, analysis and,
as necessary make measurements of film constants such as:
Heat capacity
conductivity
emissivity
surface convection
for various transmission/absorption conditions.
(b) Design and conduct tests for measurement of film
temperature at the film gate for various illumination conditions,
consider and compare several approaches such as:

Calorimeter
thermocouple
temperature sensitive paints
strain gage
(c)? Dimensional changes: Review utility of available data
for determining dimensional changes of film as a function of:
tension
temperature
humidity
processing history
storage history
Design a test program as necessary in order to separate the elastic
and inelastic changes.
(d) Grain Size: Review utility of available data to
determine effect on grain size of~film base and emulsion
processing
climatic conditions
aging
storage
Plan test program as necessary to obtain unavailable data.
