appears on them unless an I/0 instruction is being executed. As
shipped, these lines were hard-wired to the A-register (for the I/O

1=i
(but rather arithmetic operations, for example) the lines had data
appearing on them. Although the interface circuitry was designed
to ignore this data, the noise produced in the system by the continuous
changing of the lines proved troublesome. It was therefore decided to
modify the computer circuitry to remedy this. As it turned out, all of
the logic functions and signals required were available in the machine
so that the addition of some wiring was all that was required. These
fladditions were checked and appear to be entirely satisfactory, and

Two types of problems exist in certain areas of the
interface circuitry; noise and propagation delays.
By means of a ground-plane bussing system for the
?
circuit common lines, it has been found possible to reduce the noise
levels in the system to well within the acceptable levels for correct
operation.
Propagation delays primarily affect the interface between
the computer and the machine. Due to the polarities of the signals
present and needed, it has been found that a minimum of six gates
is necessary for the routing of circuitry which tests the condition of
a pushbutton or indicator on an SKS instruction. In some cases, it
was found that the number of gates could be reduced to the point
where propagation delays were inconsequential; in other cases, minor
circuitry and programming (software) changes have rectified the problem.

PROGRESS REPORT FOR PERIOD ENDING 31 JULY 1969
1.0 PROGRESS DURING REPORTING PERIOD
During July the RG 142 EVU,coax was procured, installed and
tested for the WI, W2, W5 and W6 cable assemblies. Connectors
J24 and J25 on the chassis, J2 on both image dissector assemblies,
and P24, P25, P51, P53 and the P2 connectors on the cables
were also replaced to accommodate the larger high voltane coax.
The new lines and connectors were tested on July 30 usinn a
Fluke Model 410A high voltage DC supply and a 10 microampere
meter. At 3500 volts neither, line showed a leakage above 1
microampere. The P51 and P53 bulkhead connectors to be mounted
by NRI will require "D" holes with 0.515 inch diameters (0.218
inch center to flat edge):
During July, a check sheet package was made to organize and
systematically record the measurements of Section 4.5 of the
acceptance test procedure. The check sheets will be used to
refine the procedure and should lead to a smoother performance
of the acceptance test. The task of cleaning up the software
items, however, will be subordinated to the task of debugging
the equipment to reduce the need for pursuant revisions and
addenda and intemuption of the debug cycle.
STAT
The acceptance test date was moved up to the week of September
8, since the cable replacement had introduced additional slippage.
During subsequent telephone conversations between and Itek STAT
on August 7 and 14 expressed an interest in the debugging STAT
activities. A short description follows.

The subassembly tests,'..preceding preacceptance testing,
verified:that:the originall:rdesired circuit functions were ob-
tained. Ivaddition, improvements in linearity were obtained
in the deflection amplifiers, the integrators, and the dis-
tortion analyzer weighting function. The drift rate on the
deflection amplifier was also improved over the drift noticed
on the previ.ou?orifiguration. The instability of the original
video amplifier configuration with capacitive loading was not
occuring with the added output stage and the original desired
response was Maintained. The design of the absolute-value gen-
erators used in the channel selection legic was corrected. The
video correlate/. *,configurations did not produce satisfactory
- nulls and the repair involved adjustment to the foil. This
resulted from an error carried over from the original documentation.
Also, an excessive amount of unbalanced orthogonal output was
measured at the low frequency end of the tyband. This was
reduced by driving the multipliers from a less reactive source
(increasing the size of the coupling capacitors). The adjustment
range of the raster delay board had to be changed to agree with
the stipulated range,' since this coincided with the anticipated
requirements. General housekeeping adjustments of levels and
balances made up the remainder of the subassembly tests.
Preacceptance testing began with the adjustment of the low
voltage power supplies and a rough check of the operation of
each card as it was inserted. Chassis Tiring errors were found
and corrected. The X'test and Y test outputs were connected to
a type 535A oscilloscope and these raster delay outputs were
determined to be oscillatory under the capacitive load realized
with the:use of 5.tort lengths of coaxial test cables. The high
frequency cutoff of AR1 and AR2 in the raster delay was lowered
to stabilize the circuits. NO deterioration of the sweep voltage
waveforms were noticed and a clean test raster was produced.

The image dissector assemblies were checked next. A minor keying
error was corrected and subsequent voltage checks made before
the housing was put on and-the assemblies installed on the test
fixture. The immediate indication was no video which was sub-
sequently traced to the dissimilarity of pin connectors between
the S20 and ..S11 image dissectors, corrections were made to the
wiring and. the mounted on an open frame fixture to
continue testing without the housing. Mutual coupling effectF,
were noted in the equipment '(modulation and crosstalk) which
were reduced by changing, the use of the existing decoupling
and by bypasSinthesUpply voltages.and resistive dividers.
A bar pattern was projected onto one image dissector and the
delay time settings of the raster delay board were adjusted until
a reconstructed image was obtained on the 535A oscilloscope.
It was then possible to adjust the X and Y size and,the focus
and shading adjustments.
On June 20, the turning on of the equipment was accompanied
by a cracking sound in the cable and a loss of video. The high
voltage lines were determined to be excessively leaky and a
replacement sought for them. The Abbott DC-DC converter was
not damaged.
Temporary high voltage lines were installed and testing con-
tinued. The open frame fixture made it possible to obtain a
source of usable video to be applied coherently (same video to
both inputs) or independently (both assemblies connected but
only crude alignment with images possible) to the image analysis
system.

' The video from independently operated image dissectors with
the identical targets would not match. This was.traced to the
inversion of the reference voltages applied to the left and
right associated circuitry in the sum and difference board. The
deflection coil connections were reversed to the 62 image
dissector (identified by the Si keying.on connector J1) to scan
correspending areas on both images.
The remote X and Y positioning adjustments require the
insertion of lequal and opposite DC voltages to the deflection
amplifiers to affect a synchronous motion of the two rasters.
The two inverteri. in the sum and difference circuit and four
externally connected resistors are used to add the required
voltages to the deflection voltages at the output of the sum and
difference circuit. Before this point the deflection signals
are AC coupled.
Independentivideo signals multiplied at the correlators were
effectively blocked at the channel selector, because the channel
selection logic circuit was intended to select the channel with
the lowest output. , In effect, the selection criteria used
hindsight rather than foresight, since it seeks a post-stabiliza-
tion condition rather than a processing condition, moreover, the
post-stabilization condition selection leaves the processor
open to the unbalanced correlator output, which consists, generally
of components of the deflection voltages, noise and various
other undesirable signals. To preserve the adaptive intent of
the channel selection logic, the A1 and B channels were inter-
changed and the thresholds readjusted. The following selection
criteria are used. Band B is on if OCB output exceeds threshold
I (set to the unbalanced output level).Band'A is on if OCA ex-
ceeds threshold 3 (set to the unbalanced output level )and if Band B is off

(0C8 less than unbalanced level ).Band A1 is on when bands A
and B are off (OCA and OCB less than unbalanced level). The
channel selector -how switches the appropriate band information
to the analyzers.: '
An oscillation in the deflection pattern amplitude, which
occurred with some regularity, when the equipment was turned on,
was traced to variations in the integrating time of thE sweep
reference. The time base generator output was frequency modu-
lated by the discriminator, AR2, when the initial state of Z11B
permitted the wrong phase of the sync signal to dominate. This
condition was alleviated by reducing the inverting gain of AR2.
The time base generator will be cycled over temperature and
voltage to check its synchronization and stability and determine
if additional compensation is necessary.
Current pulses in the deflection amplifier and associated
connections were seen to be introducing interference signals
into adjacent circuitry. A perforated shield was placed behind
the deflection amplifier boards and the external connections
shielded.
The video amplifiers were observed to have dissimilar pulse
responses which also raised the orthogonal unbalanced output.
The low frequency cutoff of the video amplifiers was extended
to improve the pulse response in both image dissector assemblies
and reduce this dissimilarity.
The AGC function of the video amplifier reacted to instantaneous
changes in intensity, by blanking out video signals for periods
which sometimes exceeding the frame duration. By increasing

the AGC time constant, the attack time was extended. The resultant
AGC tendency is to react on the average illumination in the frame
and the long recovery times do not occur during processing periods.
An AC threshold circuit added to the output of the channel
selector supresed the contribution of ?the remaining unbalanced
orthogonal output to the total error signal entering the analyzers.
The procedure fcr adjusting the zero offsets in the integrators,
distortion analyzers and parallax analyzers was time consuming.
A shorting board was constructed and a procedure for using
it which reduces the task to less than 15 minutes.
A check of the Weston 756 illumination meter indicated a
linear relationship exists between the illumination and the
terminal voltage of the meter. The low-scale scale factor
approximates 1.0 foot candle per millivolt at the terminals. This
relationship will be used to expand the scale during illumination
measurements at the image dissector assembly.
The integrator reset function was ineffective as long as
signals were still present at the integrator inputs. The physical
resistance of the shorting FET and its current limiting series
resistor acts as a-feedback resistor which reduces the gain --
but not to zero. An FET switch was added at the channel selector
output to shut off the signals during reset. In conjunction with
the FET is an inv.txter which accepts the correlation enable
commandrrovided by NRI and inverts it to produce a uniform
voltage levels for the reciprocal (inhibit) signal required in
the system. The gates and reset circuitry perform as intended.

The high voltage, cables were replaced and alignment and
testing continued in the test fixture. The following activities
continued into August.
The parallax reference ?inputs were reversed to provide the
correct polarity of parallax signal relative to the established
left and right assemblies. By open-loop checks, the phasing of
the modulator outputs to the sum and difference circuit and
subsequent phasing of the distortion analyzer references were
set in order. .
The adjustment for the analyzer reference delay time was broad
enough to obtain opposite polarity signals at both ends of the
adjustments. The appropriate adjustment, however, lay outside
of the existing range and the circuitry changed to enable the
correct setting and avoid the unstable range.
Measurements performed on the correlator test fixture indicate
that physical alignments cannot be maintained adequately during
slide changes etc., to verify the independence of the error
signals but an alternate means (e.g., insertion of electrical
error signals) may be more desirable.
Electrical interaction between outputs ?is presently excessive.
This crosstalk is directly proportional to the processing gain.
A minor conflict exists, since the ability of the system to
maintain error signal scale factors for a variety of information
content in the slides is also directly proportional to the pro-
cessing gain. ?

Measurements indicate that all error signal responses will be
'reasonably linear. The precise adjustment of the scale factors
will not be made,hOweVer, until the source of the electrical
crosstalk is controlled and the processing gains are set.
2.0 PLANS FOR NEXT PERIOD
Continue the debugging phase, which includes setting the scale
factors, checking out the time base generator, installing a
component board with the additional circuitry determined during
testing and improving the implementation of the test procedure.

MONTHLY PROGRESS REPORT
JUly, 1969
? This technical report is for the reporting period from July 1 to July 30,
19691 The report is prepared according to specification number DB1001
? (as modified).
? 1. At the end of the report period, all subroutines were individually
checked-out, except those mentioned in part 2 below. During
checkout several routines have been modified from time to time.
Some of these changes, naturally, propagated to the drivers,
EXEC I and STAGIN.
The blank common blocks of all routines were made congruent in
preparation for total integration of the system.
A new entry was created in subroutine CVB, called CVB1. This
entry allows floating-to-fixed point conversion where the fixed
point result is of arbitrary scale, i.e. , the location of the binary
point may be set by the user.
Because the non-real time and foreground real time programs
cannot be tested further without the interface, emphasis has been
shifted to the real time background program. There, the Earth
Curvature, partial blowups, and no camera data options have
been merged into subroutines TMAT and TRK.
As of this reporting period approximately 75% of the total contract
work has been'Complete

The following subroutines are yet to be definitively checked-out:

b. EXEC2
c. STAGIN
d. RDOP
e. RDST and
f. RDCR/X.
These routines cannot be further checked until the stereocompara.tor''s
interface and stage measuring systems work.
Next month, the real time background program will be integrated
and tested in the DDP-516.
If the interface becomes available, then the non-real time program
- will also be integrated.
The correlator crosstalk problem is outstanding; however, of low
priority.
. Apparently, several slips have put the interface and stage location
logic behind schedule. It is likely that Informatics will be unable
to find fruitful work to pass the time until these are ready for
further program testing. It may become necessary to negotiate a
new program delivery schedule.

Stereocomparator
plant was closed for their annual August
vacation during this period. The Stereocomparator work, however,
was proceeding with respect to test and optomechanical adjustment.
All the optic subassemblies are tested three times.
First, the optical fabrication department performs a test
to determine whether or not the optical characteristics of the individual
optical elements are satisfactory.
Second, the production department performs a test which
is done with care and under thorough mechanical and optical inspection
conditions. This test is made on the completed optomechanical sub-
assemblies.
Third, the completed subassembly is tested under labora-
tory conditions by members of the design engineering laboratory staff.
The greatest possible care is taken with the measurements
during this last series of tests. Usually minor realignment of the optical
elements is made at this time.

The lenses for the main zoom, the prisms for the
anamorph systems and the objective lens assemblies were completed
and were in the process of testing in their respective mechanical
assemblies. The optical aspects of the tests concerning resolution
and magnification, etc., had been completed earlier. The current
tests were related to image wander and the mechanical adjustments
of the complete subassemblies.
These various tests required individual setups involving
several telescopes, mirrors and as many as five autocolimators with
two or three light sources plus flat granite inspection tables. In
addition to the equipment, each test involved optical and mechanical
engineers and test and inspection specialists from the production group.
The tests on the individual assemblies take from two
to six weeks, during which time the optomechanical characteristics
were optimized by adjustment of the placement of the various optical
items in the overall subassemblies. These tedious and painstaking
operations were being conducted effectively during the vacation shutdown.
Further, the work utilized most of special test equipment and STAT
facilities including the most knowledgeable members of the engineering
staff.
OPTICAL BRIDGE
The three elements of therptical bridge have been STAT
completed in terms of the mechanical interface for the optical subassemblies
and the outside painting.
The optical bridge has been installed on the
Stereocomparator test fixture utilizing the ooling.

painted and the test fixture painted. There is, however, no air condition-
ing or air filtering system as in a conventional clean room. STAT
has provided double vestibule doors at the entrance and every effort will
be made to keep the area suitably clean.

plans to test the shock isolation characteristics
of the selected shipping system by transporting the completed objective
lens turret assemblies by road around Paris. Prior to the transportation
test, the equipment will have been put through the complete optical
alignment tests. Also, the mechanical characteristics of the image
wander, during focusing and objective lens switching, will have been
carefully recorded. The objective lens turret will then be placed on a
truck and driven over Paris streets including those with cobblestone
surfaces.
After the equipment has been returned to the
plant, the full series of optical alignment and image wander tests will
be repeated and compared with the values obtained prior to the transpor-
tation experiment. The results of this test will determine the design of
the shipping containers for the shipment of the optical system to Berkeley.
ILLUMINATION SYSTEM
The parts for the main illumination system have been
completed. The switchable afocal systems have been installed in the
illumination system casting but the optics, including filter discs, field
lenses, diaphragms, and mirrors are not yet installed. All these parts
are on hand. The motors, tachometers, gear reducers, potentiometers,
and electrical plugs for this subassembly are also on hand.
RETICLE ILLUMINATION SYSTEM
The complete reticle lamphouse assembly has been
completed at the Chateaudun plant but has not yet been delivered to the
Davout plant of

RETICLE 10X ZOOM
This subassembly is mechanically and optically complete
but has not yet been put through its final optical tests.
RETICLE ANAMORPH
The anamorph prisms are completed and assembled into
their four groups. The mechanical portion of the anamorph system is
completed and has been assembled and aligned. The work remaining
requires the mounting of the.prism groups and setting the optical alignment
and optical function characteristics.
RETICLE REDUCING RELAY
The 50:1 relay assemblies have been completed. Both
the mechanical and optical specifications have been checked out by the
production department and found satisfactory. The optomechanical test-
ing by the laboratory group has not yet been performed.
RETICLE LIGHT LEVEL AND COLOR FILTERS
The optical and mechanical parts for these subassemblies
are complete but the assemblies have not yet been made and the parts
are still at Chateaudun.

? .
The second anamorph system has been assembled
mechanically and is awaiting prism installation.
The work of preparing the main anamorph system mechanism
to receive the four sets of prisms is a highly complex operation involving
a series of autocollimators, light sources , mirrors, prisms, granite
blocks, etc. Once the mechanical interface is true, and the rotation
mechanism accurately adjusted for consistent angular movement of the
four, sets of prisms, it is necessary to install the prisms in their cells
and checkout the optical characteristics.
At the time of th monitoring visit, the first system
had been adjusted so that image wander during full travel of the anamorph
prism system represented 5 seconds of arc; thus with the 10X eyepiece
system, this would represent 50 seconds of arc.
Work was continuing on the system to optimize this
condition. Note, however, that the value achieved already is only
1/24th of that permitted by the specifications for the entire optical system.
This type of effort is typical of the extremely precise
workmanship which is using in building this equipment.

it was not possible to establish a status of the parts assembly operation.
MAIN BEAMSPLITTER
The image dissectors 'and light level control photomultipliers
require two beamsplitter prisms in the main optical path. These prism
parts were completed some time ago including their coating. However,
the reflectance/transmittance characteristics for the prisms required by
the specifications has not been achieved. This has necessitated repolish-
ing and recoating and retesting the prisms.
This retesting has been performed unsuccessfully three
times to date and a fourth remanufacture is now necessary.
In addition to the prisms, the system requires for the
assembly, beamsplitter mirrors and mockups of the light level
photomultipliers and image dissectors. Also, projection objectives are
required for the image dissector tubes. These parts have been completed
and mounted in the optical bridge.
MAIN IMAGE RELAY TELESCOPE
Telescopes are placed between the Pechon prisms and
the eyepiece optical switching mechanisms. These telescopes have
been completed and tested.
EYEPIECE ASSEMBLY

The eyepiece system (optical block) consists of switch-
ing prisms, light level filter wheel, and the switching shutters in addition

completed.

OBJECTIVE LENS ALIGNMENT TEST
After the objective lens turret assembly was complete,
SOPELEM made a series of alignment repeatability tests. These tests
consisted of determining image wander through the objective optical
system during the 31-nrr) focusing travel and image wander during optical
switching.
Prior to beginning the mechanical repeatability tests,
determined that the image wander was within ? 1/4 micro-
meter over 0.8mm focusing travel and within ? 1/2 micrometer over 3mm
focusing travel. The + 1/2 micrometer represents 3 seconds of arc.

These image wander tests are repeated twice a day,
before and after the mechanical excursions which are performed once
a day.
The mechanical repeatability of the lens turret was
tested by performing 40 round trip full travel rotational translations of
the turret and 40 round trip full travel focusing translations of the lens
assemblies within the turrets.
These repeatability tests are performed each morning
during the work week for a four week period. This represents a total of
20 days of tests.
These tests are quite significant when it is realized
that the guide system for the focusing travel, as designed originally
failed in an initial series of tests.
To solve the problem, an external adjustable guide
rod has been installed by and the latest group of tests is to
prove the effectiveness of this modification. The failure of the initial
design turned out to be due to deformation of the parts by aging. The
new design places the parts in a geometry which results in a system
much less sensitive to deformation of the guide system.

tests may continue to January 15, 1970.
We expect, however, that some of the acceptance tests will occur
prior to December 15th and will be performed during the
work period.
It is encouraging that the optical tests
have, in every instance to date, shown that the system outperforms
the design predictions. So far, the individual subassemblies have
not been coupled optically to each other but we are reasonably
confident that there will be no major surprises.
