the brush holders' inability to firmly hold the brushes against
side forces created by the armature.
An Inland motor was tried in place of the P. C.

The sine-wave, frequency analysis, scheme of
testing was incorporated in the program CRSTOK, and the entire
program was finally made operational. A number of cases were
run - both with the frequency analysis tests and the transient
pull-in tests. It appears that insofar as the program simulates
the optics and the correlator, the method of computation is
basically stable with the proper set of multiplicative constants
introduced. At least tentatively, a set of values has been
determined for these multiplicative constants, and it appears
that the same values may work over the whole range of optical
settings - a surprising conclusion. These results are sufficiently
encouraging that priority for this type of testing has been greatly
downgraded, and the tests discontinued - at least for the time
being.
Because of the complexity of the computer-
correlator system for controlling the optics, a number of quite
drastic simplifying assumptions were necessary in order to
formulate a practical scheme for the sine-wave testing. The
image analysis system (correlator) compares two nearly similar

images and outputs four analog signals which represent four
respects in which the two images differ from one another:
X-scale factor, X-skew factor, Y-scale factor, and Y-skew
factor. The computer translates these four signals into
commands for controlling the four basic elements of each optical
projection system: magnification, anamorphic ratio, image
rotation, and anamorph rotation. As a result the optical elements
should move in such directions as to make the two scale factors
approach the value one and the two skew factors approach the
value zero. Thus the optics-computer-correlator combination
may be looked on as constituting four inter-linked negative
feedback loops.
The computational scheme is based on an
algebraically "exact" solution of the first order projection
equations for the optical system . The solution is not computed
directly, however, but is first differentiated and then integrated.
The differentiation is done analytically, but the integration is
done digitally by the computer. Thus the net effect should be
a
that the integration cancels the differentiation, except possibly
for some additive constants, and the results should be substantially
the same as would be obtained by direct computation.* Consequently
it seems reasonable to assume that if there were no crosstalk between
*The purpose in performing differentiation and integration
is to separate the computations into a background portion
and a foreground portion.

the four output signals from the correlator then the four inter-
related feedback loops should be separable at the points of
driving the optical elements. This was one of the basic assump-
tions in setting up the sine-wave method for testing the compu-
tational scheme.
Appendix III shows a listing of the program CRSTOK
with its subroutines STATIC, OPSET, OPCOMP, and -MONITR.
CRSTOK and OPCOMP contain the computational scheme which is
used in the Stbreocomparator. STATIC and the.statements in
CRSTOK from the top of page 2 down to statement 50 (CONTINUE)
simulate the correlator. OPSET simulates the projection optics
and provides for teletype input of initial settings for the simulated
optics,. MONITR provides for operator interface via the teletype.
Statement #120 in MONITR provides the driving
signals for the sine-wave tests. This statement is the analytical
equivalent of opening the four feedback loops at the driving points
for the optical elements. Were these feedback loops not opened
then XSI (J, 2) would be the settings of the slave optical elements:
anamorph ratio, magnification, image rotation, and anamorph
rotation.. With statement #120, XSI (J, 2) become the driven values
of these same optical settings and XSS (J) are the corresponding
response values for the optical settings after going around the
feedback loops to just ahead of where the loops are broken.
BETA (J) are feedback factors which can be adjusted to control the
degree of opening the feedback loops: BETA ='O corresponds to no

feedback, or the loop completely open; BETA = 1 corresponds to
100% feedback or the loop completely closed; and intermediate
values of BETA correspond to the feedback loop being partly open.
AMPL (J) are the amplitudes of the sinusoidal driving functions in
the respective loops and (ANGL) is the angular frequency. XSD (J)
are the d-c values about which the sinusoidal fluctuations take
place.
Appendix IVa shows a small sampling of slightly
over thirty such sine-wave tests which were run. The remainder
of the curves are not included since they are all virtually identical
to one or another of the curves which are included. The very great
similarity of curves obtained for different optical settings was a
surprising feature of the tests, and ultimately led to the con-
clusion that one or more of the assumptions underlying this method
of testing must be invalid. Consequently the sine-wave scheme of
testing was discontinued and the transient pull--in scheme was
taken up instead. The latter scheme will be discussed later, but
first a little more should be said about the results of the sine-
wave tests.
The computer program tests which are being reported
here came about as a result of a realization that the portion of the
computer program which computes the optics settings corresponding
to particular correlator signals was possibly unstable as originally
designed. The original scheme was hence modified by introducing
GAINFR (K) into statement 30 of OPCOMP, where previously the

fixed value one had existed implicitly. This modification then
raised the problem of determining optimum values for GAINFR (K),
and it seemed likely that the optimum values would be (non-
constant) functions of the optical settings. Hence arose the need
to determine the nature of these functions. The sine-wave type
of testing was intended to be a systematic way of handling the
very large number of different cases which occur: Thus
GAINFR (K), (K = 1, 2, 3, 4), is thought of as being like a gain
control by which the loop gain of each of the four feedback loops
can be set. Linear feedback theory gives some well known
criteria for examining curves of open loop gain and phase shift
versus frequency and judging what the closed loop performance
is apt to be.
Figures 1 through 4 are four curves selected from
a large number of tests intended to show the effects of varying
anamorphic ratio and the two rotation angles while maintaining
magnification constant - at the value 12. The results turned out
to be that the effects were negligible. Figure 1 is highly typical
of all the tests in this series except those presented as
Figures 2, 3, and 4. The latter are the cases which varied most
from all the rest. Even the variation among these extreme cases
is not enough to be of any significance. The theory behind tests
of this type says that the thing to look at is the phase shift at
the frequency at which loop gain passes through zero db. In these
curves zero db gain occurs at about 1 . 6 radians/sec. and the

phase shift at this frequency is 110 degrees . Since 110 degrees
is considerably less than the danger value. - 180? - it appears
that the GAINFR for the magnification channel might be made
slightly, but not much, larger than the value . 05 at which the
tests were'run. The surprising indication of this series of tests
is that the optimum value of GAINFR for the magnification channel
(at least at the value 12X) does not appear to be effected by the
optical settings for the other three channels.
Figure 5 is typical of the curves run in the second
series of tests - similar to the first series - but with the magnifi-
cation held at the value 60X. All the. curves in this series turned
out to be nearly identical. Although this series included a smaller
number of individual cases that the first series, the results again
indicated that the optimum value of GAINFR for the magnification
channel does not appear to be effected by settings in the other
three channels. Furthermore the indication seems to be that the
optimum value for 60X is not appreciably different from that for
12X - another surprising result.
Figures 6 through 9 are curves obtained in the third
and last series of sine-wave tests. This series was run to check
the d".ning suspicion that the sine-wave tests, at least as being
run, weren't accomplishing the purpose for which they were
intended. This series was one with the optical settings held
constant, but with GAINFR for the magnification channel varied
directly. Since GAINFR is one of the factors making up the loop
gain, linear feedback theory says the various gain curves in this

 Declassified in Part - Sanitized Copy Approved for Release 2012/08/29: CIA-RDP79B00873AO01300010018-1
series should be similar in shape, to one another, but shifted
parallel to themselves, when GAINFR is varied. Comparing the
curves obtained shows that they shift, qualitatively, in the right
direction, but, quantitatively, by an amount which is much too
small. Thus a change in GAINFR by a factor of 10 should produce
a 20 db. vertical-shift in the loop gain curves. Figures 6 and 9
have over a 10/1 factor in GAINFR but show a shift of well under
10 db. Figures 3 and 9 should show a shift of 6 db..but have
virtually none at all. Thus it seems that the very much simplified
assumptions underlying this particular method of testing are of
questionable validity and any conclusions which might be drawn
from them would hence also be questionable. Thus the sine-wave
method of testing was not proving to be a short path to optimum
values for GAINFR. Rather than trying to perfect this method of
testing, the simpler, but seemingly less systematic, transient
pull-in scheme of testing was returned to.
The transient pull-in scheme of testing had been
tried earlier, but was somewhat unsuccessful due to the large
number of individual cases and the long time required for typing
the results of each case - as originally set up. Read-out
problems of earlier versions of the program CRSTOK were solved
only after the part of the program dealing with teletype output
was broken out into a separate subroutine - MONITR. * Several

revisions of MONITR finally resulted in the present version,
which gives the operator complete control of how much or how
little data is typed out, and with flexibility to change the
amount during the coarse of a particular run. It is somewhat
coincidental that this same version of MONITR also incorporates
the sine-wave scheme of testing.
A key factor in reducing the amount of data which
must be typed out, however, was devising a criterion by which
the computer could "recognize" an "end point" for a particular
run. It then became necessary only to type out final values at
the end of each run, thus eliminating the time consuming process
of typing intermediate values throughout the progress of each
test. An operator can, however, specify additional type-out
to verify that any particular run is really valid.
Appendix IVb is a tabulation. of the "end-point"
values obtained from a number of individual runs. In each test
the first three lines, XSI (1), XSI (2), and GAINFR, are inputs to
the program - typed by the operator. The last two lines,
XSI (2), and N are final values for the particular run - typed
by the computer. XSI (1) and XSI (2) stand for master and slave
optical settings; anamorph ratio, magnification, image rotation,
and anamorph rotation. GAINFR are the same parameters,
discussed previously, for which optimum values are being
sought. N is the number of iterations which the program makes
in order to artivd at the program determined "end point" of the
particular run. Thus, in this scheme of testing, the values of

GAINFR are strictly trial and error operator inputs. The value
criterion for any particular set of GAINFR are the accuracy with
which line 4 approaches line 1 and the smallness of N. A rough
idea of the significance of a particular value of N may be
obtained by dividing the value by 30 and considering the result
to be the time, in seconds, for the Stereocomparator to "pull-in"
from the optical settings given in lines 1 and 2. It should be
remembered, however, that this mathematical model of the optics
and correlator is probably a pretty poor representation of the
Stereocomparator hardware.
The cases which have been run to date, and shown
in Appendix IVb, are not an exhaustive coverage of the possible
optical settings, but are a pretty good sampling over the possible
range; of settings. The indications are that the same values of
GAINFR are fairly satisfactory over the whole range - which was not
expected to be the case. At any rate there does not seem to be
much doubt that suitable values can be found. Consequently
priory for running these tests has been down graded to the extent
that such tests are not presently being run, but may be resumed
when the computer is in less demand.
In conclusion, there is probably some value in
speculating as to why the sine-wave testing did not go as
expected - even though there are no plans for trying to perfect
the method. A likely possibility is that the assumption of
separability of the four inter-related feedback loops is not

valid. Under this assumption the tests were run with the
values for BETA set to 1.on the three channels being treated
as inactive in each particular test. This was thought to be
the condition most like that which would exist in the
Stereocomparator. Apparently, however, the four feedback
loops are so closely linked together that these values of
BETA exerted a strong influence on the channel being tested
(magnification in the cases which were run). It may be that
lower values of BETA on the "inactive" channels would have
resulted in the tested channel behaving more nearly as
expected. Tests with low values of BETA on all channels
would require careful interpretation however. Thus it may be
that the sine-wave method of testing would be alright for a
single feedback loop, but is not very useful for a set of inter-
linked feedback loops.

During the month of February, our efforts have been essentially
devoted to the adjustments on the reticle branch.
As it has been mentionned in our January Report, it has been
found that the optical field was too large in certain cases of magnification
and anamorph ratio and that it cannot fit with the afocal reducer.1/50 X.
A first afocal-1 X system has been designed and mounted on the
10 ratio zoom of the reticle branch. This experiment has shown that it was
necessary to make a second change, consequently a new divergent optical
element has been placed in the afocal -1 X but the performances.was still
insufficient. Then a third experiment has been made using a divergent
element in two parts, one of this lens had a non polished surface of which
the purpose was to enlarge the field of the optical rays coming from the
edge of the spot.

routines will be mated with the hardware. If this goes well,
the time tic and fiducial input routines will be thoroughly unit-
tested.
2. At this time it appears thatu is intensively studying the STAT
correlator response. A change in the program may result from..
this work. If this happens,
may submit a request STAT
for change-of-scope, depending on the magnitude of the change.

of the contracting officer.
6. Since returning to
E
has encountered extraordinary STAT
difficulty with the computer hardware (particularly the punch) and
with certain vital utility routines, written and
supplied to us
under the terms of our contract. We feel
that these matters must be resolved before we can effectively
carry out the terms of this contract.
