for monitoring the Model 552 & 552A
1. The Chip Comparator was briefly discussed.
disclosed two problem areas:
a. There is a low amplitude, high frequency vibration induced
by carriage motion in either x or y which exceeds the band width of the
interferometer.
b. The vacuum grooved glass plates, as delivered b
have not met the required flatness specifications. hopes
to solve these problems in time to make delivery by -Lu ay
2. announced the following delivery schedule for
the Model

discussed the 387 Viewer and High

Intensity. n Table developments respectively.
4. We viewed a mock-up of the Control Console consisting of a
partially completed cabinet fitted with a radial saw boom and a
plywood simulation of the eyepiece assembly. Eyepiece attitude
rotation is now accomplished through linkages between the boom and
the eyepiece assembly. The elevation position motion was altered
by a crank on the operators end of the boom -- this motion didn't
work properly. There was considerable discussion on the location of
the controls -- a degree of agreement was attained, but there was
some confusion as to the total number and type of controls required.
A composite list of controls was requested and will be furnished by
In the near future. The rough coordinate readout counters will
be transferred to the control console. Hand wheels for film advance
will be tight against the edged the top and will not protrude
above the top and intrude upon the work area. The contractor was
informed that a crank with a folding handle must be provided.
Rotation knobs with counters for joystick direction control
are planned; however, the location has not been decided. The knobs
and their associated drive linkages will be purely mechanical.
The physical position of the joystick on the console was examined..
was directed to move the stick to the rear as far as possible.
The spped control button is to be removed from the joystick and placed
on the control console. The present three-position, push button saddle
switch atop the joystick will be replaced with a single two-position
push button switch. This is to be supplemented with an auxillary,
fixed, three-position switch on the control console. The three posi-
tion switch is in effect a channel selector -- right, left or both.
The two-position switch will be utilized as a trim switch during
stereo-scanning.
5. One pair of 3/L fiber optics cables with the new plastic
casings had been received and. were available for our examination.
These cables appeared to be of good quality.

6. Examples of the smallest size laser marks, again, were not
available.' The laser is still inoperable.
7. The contractor is still working on the problem of producing
an optimum vacuum grove for film hold down nor has an acceptable
transparent vacuum manifold been developed. When the groove is
deepended the hold. down occurs with the 10 sec. limit but the
grooves are not acceptable optically. If we have to compromise,
we will give up time (hold-down speed) to obtain optical quality.
The plates have been sent back to the vendor for further polishing.
8. I Jclaims that they can obtain an acceptable
solution to the low power Illumination through the use of a field
lens between the film and the objective. We are still doubtful.
Chitayat claims that they are currently obtaining 600ft. lamberts
on the lens bench mock-up.
9. discussed the optimization of
the image integrator scan. claims there is no simple
solution to the problem but that they will investigate it.
10. The new joystick mechanism was available for examination
in an early assembly stage. It requires additional design work
before it will 'be acceptable.
11. Questions concerning contemplated velocity ranges resulted
in the following answers:
a. oil' - ill per sec. with a .004" increment in the low
range.
b. .0001" - .0l" per sec. with a .0004" increment in the
low range.
Incorporation of the 2.5mm ball screw may reduce 'the maximum
slew speed obtainable with the stepping motors to .75" per sec.
