PROGRESS REPORT
For
VERSATILE, HIGH PRECISION STEREO
POINT TRANSFER DEVICE
Work this month has been to update assembly of Point
Transfer Device and companion Stereo Viewers. Assembly and modi-
fication phases should be completed during next reporting period
while final optical and electrical adjustments are in progress on
machine to be shipped next, 552A #102. Because of the large
number of adjustments required, schemes and tools are being
standardized to get uniform and optimized performance in the end
products. Emphasis has been placed on procedures and equipment
that permit adjustments to take place on the machine rather than
in the laboratory so that installation and servicing requires the
least possible disassembly of a system.
OBJECTIVE ASSEMBLY
The Objective Assembly Optics in the Point Transfer De-
vice are in their preliminary adjustment stage. One problem ob-
served is the blue-qeen c_olor given the image by the dichroic
film in the beam splitter used to put the laser imagery on the
optical axis. Since there was great concern in the past about
the color seen at the open gate illumination, improvements to
reduce filtering of visible light will be investigated. The
problem is to obtain sharp division between highly efficient re-
flection for the laser (infrared) light path and high transmission
with the visible light that is not reflected. Because the filter
reflects more visible red light than desirable, the image has a

blue-green character. Opposing this goal is our problem to find
an arrangement to eliminate ghosts and image distortions. For
example, a piece of glass arranged at 45 degrees to the optical
path with a speciman dichroic coating on one side, and anti-
reflective coating on the other, may exhibit sharply defined IR
reflection properties but introduce a ghost and some astigmatism.
The cube eliminates the latter, but blurs the reflection proper-
ties. One solution may be to separate the members of the beam
splitter slightly, allowing a minimum of ghost spacing and astig-
matism, and creating a film-air interface improving IR reflecting
properties. i

this network has less output on some of the voltage levels speci-

fl-id width that counter requires for reliable operation. In spite
of these, customer tells ub system will work safely and reliably.
We then are proceeding to check out encoders, install in temporary
rack, mount panel switch, and will advise customer of type and
length of cables required on system for encoder connection.

It is suggested that the four (4) required electronic
modules be rack mounted to simplify installation and intercon-
nection, and should be forwarded to use for above work during
the next reporting period.
Work for Next Reporting Period
1)
Complete updating assembly work of all
machines.
2)
Continue final adjustment and debugging
552A #102.
3)
Commence final adjustment 552 #101.
