Progress Report No. 5
Period Covered: May 13, 1965 to June 12, 1965
The project is progressing in accordance with the revised schedule. New
completion date is September 12, 1965.
Experimental studies conducted during this reporting period include preliminary
tests of the liquid gates for use on the 20-foot optical bench, vibration tests,
multiple object filter tests.
Preliminary tests on the liquid gates revealed that the gates operate properly
until the liquid is added. After addition of the liquid, the gate develops an
Now astigmatism which prevents proper focusing of the image. It is thought that
temperature gradiants may be causing the problem. Various liquids will be in-
vestigated to try to get the gates operating properly.
The tests of multiple object filters will be repeated. Early tests were done with
ten object filters, comparing the filter to all ten objects at the same time. It
has been determined that a better method of testing is to check against one object
at a time. Also, the tests to determine the optimum number of objects for vehicles
will be repeated using the new testing procedure.
Vibration tests were conducted and revealed that the system will operate in the
image recognition mode with rather severe vibration. The actual exposure time to
produce a filter requires a vibration-free optical system.
All of the analytical work scheduled to be done by
and is ready for inclusion in the final report.
has been completed25X1
During the next reporting period, it is planned to complete the multiple object filter
tests, the tests of shadows and target perspective and start intensive work on target
obscuration using aerial photographs. Investigation of the problems with liquid gates
for 20-foot optical bench will be continued.

Progress Report No. 4
Period Covered: April 13, 1965 to May 12, 1965
The project completion date has been extended one month and the PERT diagram
has been revised to reflect this change. New completion date is September it, 1965.
The work is progressing on schedule. A preliminary copy of as much of the report
as is finished at this time has been submitted. This information is still subject
to change and should be handled accordingly.
Experimental studies conducted during this reporting period include:
continued work on effect of shadows and effect of image scale (1 mm objects), effect
of number of targets in one spatial filter, and image packing density.
Curves were prepared of the effect of shadows using 1 mm objects. These curves
now show a definite relationship between shadows and recognition. Earlier work in
Nmethis investigation failed due to improperly photographed models.
25X1
Investigation of multiple object filters has revealed that all multiple object
filters give weaker signals than single object filters. The alignment tolerances
(x,y, rotation, and magnitifcation) become more critical. Because of the critical
alignment in rotation, the time to make a scan with a multiple object filter is
longer than making individual scans with separate single object filters. Work on
multiple object filters will continue during the next reporting period.
has investigated the relative advantages and disadvantages of using
glass plates or film for spatial filters. In all cases the film filters were better.
Although scheduled to be completed later in the program, image packing density
has been finished and reported. Optimum size appears to be 3 mm - 5 mm vehicles.
This size, of course, is dependent on the "f" number of the readout system.
Reports covering six investigations have been submitted by
completing the current work that has been outlined for him to do on the pro ram. All
these reports have been reviewed and edited and returned to Ifor comment. 25X1

During the next reporting period work will continue on the effect of shadows
using 1 mm objects and the effect of target perspective. Work on the effect of number
of targets in one spatial filter and the effect of vibration will be completed and work
will start on target obscuration.

Experimental studies conducted during this reporting period include: effect
of shadows, effect of image scale (1 mm objects), effect of alignment/tolerance, and
filter properties tests and study.
Image recognition of 1 mm size objects was attained on the 6-foot optical
recognition system. Additional microflat plates were prepared of 1 mm objects at
different sun angles. Tests will be made on these plates to determine the effect
of shadows.
25X1 has prepared a theory which will allow one to calculate the
alignment/tolerance of almost any spatial filter. Ryas determined that when the
filter position is within one mil off-axis, the signal will deteriorate to about 9/10
of its normal value.
In filter properties tests, the effects of variation in target orientation and
the effects of time constants were studied. For all different shaped objects, the
shape of the curve on variation in orientation is the same. In the case of every
object, when rotated 10, the signal fell off to 95 - 967.. The rotation can drop down to
about 60 or 70 before it has a serious effect on the- signal.

Progress Report No. 2.
Period Covered: 5 February to 12 March
Work has progressed in accordance to the PERT diagram submitted with
Progress Report No. 1. We are on schedule at this point in the work program.
The simulated photographs have all been taken and spatial filters constructed
for the majority. The results, particularly with the longer focal length optics on
the 20-foot optical bench, have been quite good. The size of the object to be
recognized and the focal length of the lenses employed can be related to give an
e'quivalent "f" number. This number should be high; in the order of 400. Some of
the images used with the shorter focal length bench have been large enough that they
violate the "f-400" rule and recognition was poor. We have also observed the effect
of dust and other particle matter as recognition is attempted of small low-contrast
images. In general, particles create diffraction images which can block the
recognition signal. The obvious solution is extreme cleanliness and careful
handling of the film.
Experimental studies conducted during this period included the effects of
_glass plates in the optical system, effect of multiple targets, target perspective
and shadows, recording materials study and filter location tolerance.
The experimental study of the effects of glass plates indicates that for
larger image formats on glass plates, the optipal flatness of ordinary plates is not
..adequate. Measurement of these differences in signal-to-noise will be postponed
until the television readout can be employed to scan the entire plate and measurements
move easily made.
