PROGRAM STATUS
Summary as of July 31, 1968
Scheduled percentage of program completed - 20.9%
Actual percentage completed this date - 18.1%
The percentage of planned completion actually achieved
this month has been diluted by 1) delay by the prospective Image
Analysis System subcontractor in preparing an acceptable proposal
(problem of adequate acceptance testing), and 2) a strike at the
French optical subcontractor's plant (resolved in June) causing a
delay in initial progress.
Program management is applying major effort in these
two areas and it is planned that the difference between scheduled
and actual performance will narrow in future reports.
manufacturing continues to maintain the schedule
with the majority of parts completed and in inventory.
Clean room construction is progressing, and bids have
been received for the required equipment.

The
design for removal of the condenser was STAT
dependent on the slot running at 90 degrees to the optical bridge.
Since this was not so, the condenser could not be removed from the
Stereocomparator without a complete dismantling of the optical bridge.
It was pointed out to them that certain minor changes in the flange
dimensions of the condenser mounting, together with a technique
for disassembly, would allow removal of the condenser, by removal
of the glass platen only.
The removal of the glass platen would require removal
of the platen holder, which in turn, supports the film drives, and film

2. Removal of Infrared Heat
To remove infrared from the main illumination system,
has arranged a mirror that reflects infrared but transmits
visual light energy. This is located immediately after the primary
condenser. The mirror reflects the heat back towards the 450 watt
high pressure Xenon enclosed arc lamp.
The system contains three additional mirrors of the
so-called "cold" mirror type whereby the infrared energy is trans-
mitted and removed from the system and the visual energy is reflected
by the mirror.
3. Tooling for Final Testing
has designed an arrangement for mounting the
supplied optical bridge, together with the necessary mounting
supports for the illumination system and other portions of the
Stereocomparator. The design is based on the use of a reinforced
concrete form, essentially appearing similar to our Stereocomparator
with built-in mounting plates for the various elements of the
Stereocomparator optical system.
They have built a complete wooden model of 1/4 scale
for the design they envisioned. The model was very well constructed
and painted to show the various elements of the system.

2 2 . Adjustable Diaphragm
The variable diaphragm aperture for the main illumination?
system is controlled by a cam with two special profiles. One profile
relates to the 40mril objective lens and the second profile relates to
the 80mm objective lens. It is thus necessary for the drive mechanism
to select the appropriate profile as the respective objective lenses are
turned into position. In addition, there are different dead zones at the
two ends of the cams and a dead zone at the center of the cam. These ?
dead zones are related to the cam driving mechanism and .not to the
condenser positioning function.
The driving system for the cam rotates through 360 degrees
with no provision for over-travel. In addition, there is a severe space
limitation and the potentiometer was required to be of minimum diameter.
This dictated a miniature 10-turn potentiometer which was found to be
available in the CIC catalog with an accuracy range of 0.1%. This
potentiometer would be geared into the system in a ratio of 10 to 1,
using precision servo type gearing.
There is no provision for over-travel in the system,, This
situation would have to be corrected by proper commands from the main
zoom system to which the diaphragm servo is slaved.

23. Main Zoom Servo
In studying the servo system of the main zoom, it was
found that there were no provisions for switching between cam segments
on the servo items slaved to the zoom, nor did the gearing for the main
zoom potentiometer conform to the zoom driving cam. That is, the Cam
required 720 degrees of motion to give the zoom lenses full travel.
The zoom potentiometer also rotated 720 degrees. This
would have resulted in the same output appearing twice in each cycle
of the cam. There was likewise no provision for over-travel. The
design also included a small Globe motor which did not have
the capability of producing full travel of the zoom system in the three
seconds that had been stipulated for all systems.
A new motor was therefore provided in the design, a
Servalco F9M2
Is required to perform revisions to the
mechanical design of the zoom drive and potentiometer system. The
new system will include one set of potentiometers rotating 360 degrees
as the cam rotates 720 degrees for the purpose of zoom position readout-
and zoom servo control.
In addition, there will be a set of potentiometers revolving
180 degrees as the cam rotates 720 degrees. These potentiometers are
for the purpose of controlling the slave servo systems on the diaphragm

and condenser systems. These latter potentiometers must be of a type
where the position of the sliding contact can be adjusted with respect to
its driving shaft. This is to accommodate the individual position of the
slave cams.
In order to provide a means for controlling over-travel
will provide a pair of microsw itches, one at each end of the
cam travel. These are arranged so that 12% before the end of the cam
travel the additional microswitch will be activated. This will provide
a means for reducing the drive velocity as the end of the cam position
is reached.
Because of the additional potentiometers required for the
control of the diaphragm and condenser systems and including the
additional microswitch contacts, a larger Cannon plug has been speci-
fled to
The new plug was an MS-3102 A-36-2011-66. This
plug would contain 52 No. 16 contacts, with four No. 12 contacts and
provides for a reasonable number of spare contacts.
The same system of linear potentiometers is required for
the control of the diaphragm and for control of the condenser for the main
illumination system. These potentiometers turn at 1/4 the speed of the
Omain zoom cam, that is, the potentiometers turn closely 349 degrees for
720 degrees of revolution of the zoom cam.
Two potentiometers are required for the film condenser.

objective lens is in the system. The other is switched by the turret to

operate when the 80mm objective lens is in the system. The two
potentiometers are independently adjustable, one to the other, with
respect to the driving shaft. They are arranged so that the output of
one potentiometer reads in the range of 0 to 5 volts while the output
of the second potentiometer reads in the range of 5 to 10 volts. The
exact voltage values are functions of the condenser drive cam over
each of its two ranges. A similar arrangement is required for the
adjustable diaphragm driving cam. On a theoretical basis, a single
pair of potentiometers would drive both the condenser and the dia-
phragm; however, this would allow no flexibility whatever in trimming
the system, and is felt to be an unwise restriction. Four potentiometers
have been required, therefore, for each of the main zooms. The model CIC
Series 170 or 200 (clamp lug mounting) would be satisfactory for this purpose.
The potentiometers for the balance of the servo systems would
be arranged to turn one revolution (approximately 347 degrees) for two revo-
lutions of the zoom cam, or 720 degrees. The suggested stack of poten-
tiometers would be of the multiple cup type:
1) One with a special taper for brightness control with
respect to film peaking.
2) A linear potentiometer for the reticle zoom 10X command
to the servo system.
3) An exponential potentiometer for the main zoom position
readout to the computer servo system.
An exponential potentiometer for the panel meter as a
readout for the zoom magnification.

working in opposite directions, is to be equipped for linear density
change with respect to the position of the wheel. This cannot be done

30. Reticle Illumination
has decided in consultation with the
Company that the XBO 75 watt high pressure Xenon lamp would be un-
satisfactory for illumination of the reticle. The reason given was that
the arc is short and of high intensity and does not remain in a fixed
position within the envelope of the lamp. This would present optical
difficulties in that there would be flicker which would cause intensity
changes to the reticle spot. It is therefore being recommended that a
lamp with a straight mercury high pressure vapor arc of 100 watts rating
be utilized instead.
This presents a problem in that there is no red light present
in the mercury spectrum and consequently when the red filter is switched
into position, the reticle spot will not be red but will be dark. The only
solution at the moment seems to be to change the color of the reticle to
yellow.
is to do some thinking on this subject and see if the problem
could be resolved in any other way. At the moment the 75 watt lamp is
unsuitable and the lamp wattage is presently set at 100.

hardware items produced would have to be demonstrated as part of the
monitoring effort. Technical difficulties would be reviewed and any
interface problems would be discussed. The design department would be
called in to assist with any problems of a technical nature.
It is clear that it will take a few of these monitoring visits
to establish a rapport similar to that achieved with the design group.
