#552 PROJECT REVIEW
STAT
VOW
ATTENDEES: Customer Representatives
DATE: 3 April 1964
SUBJECT: Summary of Topics Discussed
1. Eyepiece mount questioned. Radial arm saw design stated,
although articulated eyepiece joint use was not settled.
2. what about low power field. lens? Stated that field lens on
top of film may be manually adjusted. Discussed where lower
field lens location had more severe space shortage than the
top field lens with need of reducing scan distance x and. Y,
2 3/4 inch to 3 1/4 inch, with associated electrical complexity.
Optical distortion and poor resolution are problems to solve
with field lens above film. Possible mechanical center to
center distance, 4 1/4 inch in low power, although Y travel
should be unimpaired.
3. Noticed ribbon pattern in enhancement of fiber cable in 387
Viewer. Perhaps scan diameter covers an integral number of
multifiber widths, causing "reinforcement", or increased
visibility of cable structure.
4. Controls: Stated set up -- joy stick in right hand with
two (2) switches:
a) R-B-L channel suppression
b) fligh speed scan engagement
Layout of left hand group will have a lot to do with dis-
placing of grip controls.

5. joy Stick on 552: What is fundamental problem of having joy
stick on point transfer device (as apposed to their use on
viewers 552A)? Customer will have to determine joy stick
success here, mock-up desired may 15, was discussed. Will
hear from customer to decide if mockup and its limited purpose
will be useful,
6. Check on 552A Encoder, (order modification to Navy Viewer).
Statement of accuracy of viewer without special reworking of
way straightness, screw lead, etc. What least count encoder
would be practical with system as it is now designed? The
above answers should be forwarded to Navy so they can decide
to change encoders.
7 Laser marking sample to .001 given to P.L. They still desire
to 5 micron c1iarneter samples.

PROGRESS REPORT
For
VERSATILE, HIGH PRECISION STEREO
POINT TRANSFER DEVICE
This report covers the progress and work performed on
subject Point Transfer Device for the month of march 1964.
GENERAL
Engineering and design is 80b complete with the exception
of certain work required on the high intensity light source vacuum
film holddown and electronic control consoles and superstructure.
manufactured parts are approximately 70o complete.
Subassembly work was carried forward.
Close control and continuous monitoring of all components
and assemblies are being enforced.
OBJECTIVE
Subassembly work on the objective turrets was continued.
System labortory tests were continued.
EYEPIECE
Subassembly work was continued on the eyepiece optical
system, Additional design investigation was continued on the
feasability of an articulated eyepiece joint. The problems with
the present geometry of the eyelens optics making little space
available for articulated mirror levers or.gearing.

SUPERSTRUCTURE EYEPIECE SUPPORT
Layouts and assembly drawings are complete pending
articulated joint requirements.
BASE FRAME
Initial inspection results were excellent, In-house
painting of this frame is planned to expedite the assembly schedule.
CARRIAGES
X and Y carriages are ready for assembly except for
painting of X carriages.
LEAD SCREWS
Lead screws are scheduled for 1?4ay delivery.
DRIVE MOTORS
New drive motors with greater torque have been ordered
because of minimum backlash loading requirements. Delivery is
anticipated for mid June.
LIGHT TABLE
Castings Light Box Frame
Machining was completed. Castings were pre-
pared for final finish.

Film Loop Former
Subassemblies ready for final assembly.
Vacuum Manifolds
Layout design were continued. Vacuum plates
are being evaluated.
Vacuum Platen Glass
IVW
Sample platens were checked and found to have
excellent optical characteristics. Functional checks indicate a
variable film pull down or flattening time range between 10 and 40
seconds. Efforts are being devoted towards reducing this time and
minimizing microgroove visibility.
General Illumination
Lamp banks and controls were inspected and
found to provide only a 7:1 brightness control range and lower
brightness than required. These are being modified and adjusted
for maximum range of flicker-free illumination control.,
HIGH INTENSITY LIGHT SOURCE
The design is being finalized and experimental parts
were readied for functional checkout. Severe mechanical clearance
limitations have hampered complete solution with high intensity
light source. Low power range requires a field lens abore or be-
low film plane for desirable light distribution but causes increase
in minimum center distance of optics or electrical limit circuit
complexity. Detailed study is under way to seek a solution here.

MAIN CONSOLE
The.main viewer console closure has been designed,
purchased and is being prepared for final machining. Writing top
has been designed and purchased, and control panel layout studies
were continued.
JOY STICK
Casting and parts were manufactured. Layouts were con-
tinued and will be ready for final detailing of panograph linkages
coupling the two joystick mechanisms. Joy stick axes will be
manually driven in rotation.
ELECTRICAL SCHEMATICS - WIRE DRAWINGS
These are 50 completed, Long lead electrical components
have been purchased. Pre-wiring and cabling layouts were started,
ELECTRONIC CONTROL CONSOLES
Initial layouts were started.
Work to be completed During Next Reporting Period
1. Continue design and detail work.
20 Continue check and test mechanical and electrical subassemblies
as they are completed,
3. Continue alignment and tests,
4. Start work on additional subassemblies.
5a Continue to monitor all phases of program.
