COHERENT LIGHT EN1ARGER AND SPATIAL FILTER
5th Progress Report: 1/ Oct to 15 Nov 63
Briefly, the project has made a great deal of progress during the
e- past month and is on schedule in regard to all critical items. Higher
priority work In the house has tied up sone manpower and equipment. but
the schedule is euch that revisions are possible without affecting the
deliVery date. Iteaw of interest:
1. The basic structure, a pipe and channel meldment, has been
designed to permit convenient entrance to the customer's facility (length
9?1 1/2") end has been released for fabrication.
2. Layout of the liquid-cell film transport area is about two
thirds conplete. Air knives, related air compressor equipment and
special viten seals have already been ordered. Only minor auxiliary
items have not yet entered the layout stage.
3. Designs of all lens cells are either in the final detailing
stages or have been released for fabrication.
4. All optical designs have been completed and drawings have been
releesed to Nanufacturing. Because of the exceptional quality of surface
finiah required on these elements, special procedures and equipment must
be devised. However, the optical shop is confident of its ability to
deliver to our specifications and in agreement with our schedule.
3. The mechanical arrangement and control requirements of the en-
larger are now sufficiently final so that work on the electrical schematic
and packaging may begin. This is scheduled for 18 November.
6. Work on an electronic focus indicator is continuing, concurrent
with design of Lover rods for mechanical focus. A shipment of equipment
from the vendor is expected next week and will be tested shortly.
7. Low and medium contrast test targets were received and immediately
used in experimentation. Resolution in both laser and incandescent light
?
was higher than expected, the laser light giving the better results of the
two. Work on these expericiats is continuing with every effort being node
to provide results free of any ambiguities. Sine wave targets are also
to be used to determine the transfer functions. The customer will be in-
vited to review our results when these experiments have been completed.
8. A room has been set aside exclusively for the construction of
the prototype. This room has been cleared of previous contents and is
now being outfitted with assiembly benches, etc.
In addition to the above,work is being done on spatial filter con-
struction and theoretical studies of liquids, diffusers and glass quality
requirements.

COHEAENT LIGHT ENLARGER AND SPATIAL FILTER
4th Progress Report: 9 Sept to 10 Oct 63
0020040-7
The engineering analysis meeting and the customer review
were held in the latter part of September and at both meetings the
results of our efforts, especially the breadboard experimentation,
were looked upon with encouragement and helpful suggestions. Accordingly
there vas initiated an increased effort which was marked by the
addition of one engineer and three draftsmen-designers to the previous
personnel. To coordinate this effort there was a meeting held at
which el tentative schedule was determined for the eleven weeks
beginning 30 September: During these eleven weeks all mechanical
design ls to be done and all drawings released; experimentation is to
continue with emphasis en diffused coherent light effects and spatial
filter evaluation. .
4echanica1 design is at present concentrated on the liquid
cell-film ::ransport section which became the major design area when
the customer stated hie preference for a roll film input capability.
Work is else proceeding oil a system layout and a modification to the
output film bolder. Ail standard items such as power supply, electric
shutter, etc? have been ordered.
An optical deeign of lens #2 has been completed and the
elements detailed. Release is pending a check of glass supplies
on ban& Designs of lens cells, mounts, and focussing arrangements
tree in progress,
