Progress in Dry-Silver Program

?
The NPIC sponsored development of high resolution, dry process
photographic media is continuing to demonstrate progress. The latest
advance is the completion of an Air Force-funded, NPIC monitored, High
Speed Dry Processor based upon design principles formulated under a
previous NPIC development. The processor is designed to develop pre-
exposed dry silver film and paper as well as dry diazo film and paper
utilizing heat alone. The unit does not require chemicals, water or
plumbing connections for operation and can process at speeds of up to
100 feet per minute. Two other units are being fabricated for the Air
Force by thel in order to expedite the operational evaluation
of the new heat processed system. The first unit will soon be delivered
to Westover Air Force Base for test and evaluation. The Project Officer

Rapid Alignment Device Now Being Tested
Undoubtedly many of you have experienced the difficulties involved
in obtaining stereo from two images that differ anamorphically; i.e.,
the X and the Y scale are not the same. The Rapid Alignment Device
recently delivered to NPIC by the
will make this task easier. The device can be mounted on the
anamorphic eyepieces designed for use with the Zoom 70, Zoom 240 or
High Power Stereoviewer. The left and right images are superimposed
and viewed through a monocular eyepiece, thereby allowing the operator
to observe the relative effects of adjustments made with the anamorphic
eyepieces upon the left and right images. One image is passed through
a green filter in order to make it more readily distinguishable from
the other image when the two images are thus viewed. The green color
of the one image accentuates the red to yellow hue of the other image
(depending upon the light intensity). This makes the two images even
more distinguishable.
This device is currently undergoing test and evaluation.
Rapid Alignment Device is unclassified, but the contractual association
of the Agency with the manufacturer is Confidential.

Air Bearing Used. on Mensuration Device
?
The Micron Mensuration Stage is a unique, precisely built sta e
designed to perform accurate mensuration tasks when used with the lI
M-5 microscope or equivalent and an appropriate computer. The stage
uses an air bearing concept that allows smooth movement in both the X
and, Y direction. The air bearing is complimented with a precise roller
bearing drive so that both coarse or fine positioning can be quickly
obtained.. Optical encoders provide a plus or minus one micron readout
accuracy. One of the many features of this equipment is that it may be
turned off in the middle of a measuring job and turned. on again the next
day without recalibrating or resetting the zero point. Distances of up
to 100 mm can be read in both the X and Y directions. The Micron Men-
suration Stage has been developed by the Rome Air Development Center
under contract Ten units are already in use and,
additional devices have been procure l. This is not an NPIC development.

An Interesting Technique for Viewing Large Areas in Stereo
By placing a mirror on the bridge of your nose and. viewing the
above right image with the right eye and, superimposing the left image
as seen through the mirror with the left eye, a stereo effect can be
achieved. This well-known technique can be used. to view large areas
in stereo. The next time you order enlargements, order a correct
image of one of the stereo pairs and. a mirror image of the other one.
Have the two photos dry mounted. on separate boards and. spray a clear
non-gloss enamel on them to reduce glare. By properly positioning the
two photos and the mirror, small distortions of obliquity and scale can
be corrected and the two images can be viewed, in stereo. A front sur-
faced. mirror of at least 3 by 5 inches in size is preferable, but any
mirror will work. This technique can be observed. on a rear screen
projector in Room 5S-453 by contacting
