Stereo Comparator
Statement of Work
Granite and Ways for Stages
The design must be coordinated with all mountable components,
i.e., air bearings, drives, film transport, laser interferometer, etc.,
for determination of flatness, perpendicularity and parallelism tolerances,
space requirements, and requirements of mounting hales and brackets .
Design goals- for flatness of bearing surfaces and ways will be 50 millionths
of an inch, also bearing way straightness and orthogonality better than
.;~ seconds of arc (9.7 x 10-6 radians).
The pitch, roll and yaw of the top stage must not produce a
combined tilt error greater than 1 second of arc on any axis within the
operating area of 10" x 24" .
Upon the completion of preliminary design a single system of
base, stages and ways will be fabricated and assembled into an operating
entity (e , g . , a breadboard of one half of the Stereo Comparator system) .
This equipment will be used for testing the air bearings, stage drive,
interferometer, etc., and their associated electronics and control systems.
On the completion of testing, a detail design for the dual stage
system for the Stereo Comparator will be completed.

Statement of Work
Air Bearings for Stages
The preliminary design, fabrication, and testing of air bearings
applicable to the Stereo Comparator high precision stages and drives will
b? performed prior tc~ d?etailed design.
The above testing work will be in conjunction with the stages
and drives experimental testing.
r`""'~ The design goal for the bearing stiffness will be 4 pounds force
per square inch of bearing surface, per micron of bearing gap deflection.
Should the stages require load compensated bearings, then a
suitable load compensating device, for each bearing, might consist of
sensors which typically might consist of gap sensors, differential pressure
sensors, load sensors, flow sensors, or combinations of these or other
types of sensors, to sense the change in lift off gap. Then a means of
transmitting this information into a pressure and/or flow increase or
decrease to maintain the lift off and stiffness gap to within the tolerance,
Note that any air flow noise must be minimized.
r.+
The main loads that will be encountered will be the accelerating
and decelerating loads, the translation loads of the masses of the X and Y
stages, and the loads due to the film exchange from one spool to the other.
The maximum acceleration and deceleration is estimated at
10 in/sect and the weight is estimated at 700 lbs .
The film exchange load will change from 0 lbs ., empty spool to
approximately 20 lbs.- full spool of 9-1/2" .wide, 500` roll film.
After successful development and testing of the air bearing, a
detail design will be accomplished, applying the air bearings directly to
the Stereo Comparator stages as required.

The point finder is used for rough location of a point of
interest on the film. The coordinates of the point will be stored in
the computer for future recall. Upon recall, the point will position
directly under the viewing optics objective..
The point finder will indicate an area approximately 1/4 inch
in diameter on the film, to be visible to the operator, and at a known
fixed distance from the viewing optics objective. The stage travel.
in the long dimension (towards the operator console) must be sufficient
so that the rear end of the film platen may be moved forward of the
optics bridge for unobstructed direct view.ing during alignment with the
point finder reticle.
Coordination with the film transport, the stage drive, and the

image analysis (correlation) systems. The secondary requirement is as
an input to the closed circuit TV monitor system. The optical pickup
point is just ahead of the eyepiece -hence the image scanned is
essentially that seen by the operator.
The resolution should be as high as practical -consistent
with the scanning rate used. Scanning rate should be at least 60 frames
per second as a desigri goal with consideration given to the practicality
of 120 frames per second. The video bandwidth should match the space
frequencies of the optical image (estimated at 100 to 40000 elements per

Based upon the above, the type of photo pickup device will

upon the factors described. The task shall include signal through video
amplifier output, ready for correlation inputs . Note that one complete

8. All other required components, i.e., field lenses,
mirrors, prisms, etc., will be packaged for ease of
installation and support.
All optical packages requiring internal actuation will be furnished
with external means for attachment of drive motor as specified.
MAGNIFICATION
From object to eye, continuously variable from lOX to 200X,
continuously in focus (closed zoom). Eyepiece magnification
approximately 10X.
VIEWING OPTICS
Viewing will be by microscope binocular eyepieces which will pro-
vide maximum operator comfort... The angular field of the eyelens
station is to be at least 35? and special consideration must be
given to eye relief, exit pupil, and field flatness, for ease of
viewing. The eyepieces shall be adjustable to include but not
be limited to the fallowing adjustments:
1. Adjustable interpupillary distance from 50mm to 75mm.
2. Adjustable headrest.
3. The eyepieces themselves are not to move either vertically.
or horizontally to accommodate optical adjustments.
4. Axes of eyepiece lenses should be slightly convergent to
aid in stereo viewing.
The design shall include optical switching by reversing the eye/ob-
ject station viewing relationship (left eye to right stage and right
eye to left stage) , and to provide binocular monosCopic viewing of
either the right or left stage, all with minimum light losses . There
must be no reversal of the image on switching between left and
right eyes -- that is, the orientation of the photograph should remain
the same for all modes of viewing, In binocular manoscopic viewing,
components .must be designed that equal light intensity is presented
to each eye ,

RECTTCLE
Provision must be made for introducing a reticle pattern into each
optical train before the light passes through the rotator or zoom
lens. The prescribed method is to have an objectives immediately
above the film, form a first image at about 10X. The reticle will
be combined with this image by a beamsplitter above the objective,
1) Functional Description
The reticle image is intended to mark a particular point of
interest on a given photograph and also serves as the reference
for mensuration procedures between points . Hence s its loca-
tion is critical with reference to a particular viewed image
point regardless of what optical operations are performed on
the image by the view system.
More detailed specifications in the following paragraphs are
based upon this functional description.
Z) Shape
The reticle image shall be a luminous circular dot compensated
for the anamorphlc correction in the main optical path,
3) Size
The size of the reticle shall be variables from a diffraction
limited minimum to a maximum of 1 millimeter diameter at the eye,
4) Brightness
The luminosity of the reticle image shall be independently con-
trollable to provide satisfactory contrast to the viewed photo-
graphs and to accommodate any apparent variations in luminosity
which may ensue from variations in size.

5) Size Coupling
When the reticle image is set for a given size in the eye field,
any change in magnification from the zoom setting shall be
accompanied by a compensating change in the reticle size.
The subtended reticle diameter in the eye field shall remain
constant. This requirement implies a coupled variable iris
at the appropriate location in the reticle projection path .
RESOLUTTON
The image quality available to the operator should, at all magnifi-
cations, approximate that of a high performance microscope with
respect to; aberration corrections, field size, field flatness,
contrast and resolution. The design goal for resolution shall be
eight lines per millimeter per power at 10X, decreasing linearly to
five lines per millimeter per power at 200X, as presented to the
observer. That is, the resolution at lOX setting is 80 lines/mm,
and at the 200X setting is 1000 lines/mm.
IMAGE ROTATION
K mirror systems will be included to provide independent and un-
restricted image rotation for each image. These K m irrors must be
located in regions subsequent to the zoom lenses and in which the
light is collimated.
ILLUMINATION
Each optical train will be furnished with an adjustable high intensity
illumination source consistent with good optical practices and
insuring as a design goal that adequate intensity is available at
all magnifications .
Appropriate cooling will be provided as part of the illumination system,
to insure that the film will not be degraded by heat, The color
temperature of the source shall not fall below 3400?K at any intensity ~,
level.

ANAMORPHIC ELEMENT
An adjustable anamorphic system with a squeeze ratio of at least
1:2 shall be incorporated into each optical train. The anamorphic
system shall be capable of unrestricted rotation in either direction
about its optical axis . This shall be located in a region sub-
s?quent to the image rotator and in which the light is collimated.
Each anamorphic system shall consist of two cylindrical lenses
with a fixed squeeze ratio (1:1.5 is suggested) . The variable
ratio will be produced by setting the angle of one cylindrical lens
with respect. to the other:
