INTRODUCTION
Proposal No. SME-CG-58
5 March 1966
This revised proposal for the Light Table with Mensuration Scanning
Stage has been prepared by
n response
to the recommendations resulting from the originally submitted pro-
posal, Proposal No. SME-CG-55. is particularly
well qualified in the engineering technologies which are essential for
successful design, development and fabrication of the required light
table. Of particular value in the proposed program is
extensive experience in developing equipment for image interpretation
systems with mensuration, such as the Multi-Sensor Viewer. Based
upon this background, can offer assurance of repeating of
high-quality picture illumination and reliable dimming control in addi-
tion to the new-added _features.
1.2 BRIEF DESCRIPTION
The Light Table with Mensuration Scanning Stage, as shown in
Figure 2-1, is a table top unit which presents approach
to efficiently adding the capabilities of a Mensuration Scanning Stage
to the Twin Light Source Stereoscope Light Table. This scanning
stage has extremely smooth movement so that the imagery does not
jump when viewing through a microscope while moving. The mensu-
ration capability, provided for each axis, has an accuracy of +0; 001"/
inch, with the capability for reading or interpolating to the nearest
0.0001".

Proposal No. SME-CG-58
5 March 1966
1. Elimination of the tilting arrangement of the original
Twin Light Source Stereoscope Light Table.
2. Reduced weight and size of Light Table compared to
original unit.
3. Increased size of light source and higher brightness
to accommodate a wider variety of stereoscopes.
4. An adjustable slide for the microscope/stereoscope
support post to allow the light table to accommodate
a wide variety of stereoscopes and rhomboid assem-
blies having different reach and coverage.
The light table is 18-3/4" deep x 20" wide x 6" high at the top of
the power supply housing in the rear and 3" high at the scanning
stage. The on-off and dimming controls are located on the sides
of the power supply housing. The scanning stage controls are
located on each side of the light table, approximately 10" from
the front, for easy operation while looking through the microscope.

LIGHT TABLE DESCRIPTION
2.1 OVERALL CONFIGURATION
The Light Table with Mensuration Scanning Stage, as shown in
Figure 2-1, is a table top unit which provides the divided viewing
surface directly in front of the operator. The viewing controls
are conveniently located on the sides so that the top of the power
supply housing is smooth and film can be laid upon it without dam-
age. This also provides easy operation without interruption of the
viewing operation when actuating the controls. The viewing surface
is split about its front to rear centerline, so that each 6-inch x 6-
inch viewing area becomes independent light sources when the parti-
tion is inserted. This permits stereo viewing with differing densi-
ties or with differing scales. The scanning 'stage is fastened to the
sides of the main casting, so as to not inconvenience the operator
by further projections toward him. As shown in Figure 2-1, the X
and Y positioning controls are conveniently located on the sides, ap-
proximately 10" from the front, for easy actuation by the operator
while looking through the microscope. The X. positioning control is
on the left and the Y is on the right. The stage is positioned by pre-
cision micrometer lead screws which are geared to mechanical
counters so as to provide easy to read digital output measurements
of imagery.
2.2 ILLUMINATION SYSTEM
2.2.1 Light Sources
The light sources are similar to those previously used. For increased

coverage it is now proposed to use two 6-inch wide x 6-inch deep
viewing surfaces directly adjacent to each other for ideal usage
as a larger 12" wide x 6" deep single viewing surface. The two
light sources are high intensity, cold cathode grids. These grids
are interchangeable, are not potted or encapsulated, and are easily
replaced by relatively unskilled personnel using a minimum of the
common hand tools. Although the cost of these high intensity, cold
cathode grids is considerably greater than that of the standard
fluorescent tubes, the advantages obtained result in far greater
overall value. These advantages are:
? Service life of 10,000 hours.
? No deterioration from frequent on-off cycling.
- Minimum height can be realized for table top
utilization.
- Simpler wiring and circuitry, therefore, much
greater reliability and down time.
- Assurance that illumination is always even and
uniform since perimeter grid can be made closer.
- Assurance that the light source will age
uniformly and not deteriorate rapidly with
on-off operation.
As before, the light sources will be sufficiently diffused such that the
variation in intensity will not exceed ?5%- as the working surface is
scanned along a line which is perpendicular to the light grids. The
temperature of the light table will not rise more than 15GF after ex-
tended use (6-8 hours). The air vents will be baffled to prevent

light from shining into the operator's eyes or the eyes of anyone in
proximity. Since these new light sources will provide higher bright-
ness, 2,500 ft-lamberts as against 2,000 ft-lamberts, there will be
about 5 or 6 degrees higher temperature rise. However, the insu-
lation provided by the scanning stage should compensate for this
temperature rise. The total viewing area is approximately 12"
wide x 6" deep with the diffuser being a single piece of opal plastic.
As shown in Figure 2-1, the light baffle, which separates the two
grids and prevents light from spilling between the two grid areas, is
easily removable. A unique feature is the easily removable light
source chassis. It is only necessary to loosen the 4 screws, shown
in the front, to slide out the light grid for replacement.
2.2.2 Viewing Light Controls
Another advantage available with the proposed cold cathode grid
viewing light sources is the highly reliable dimming control,
which can vary the brightness over the entire range without any
flickering, as usually occurs with standard fluorescent lamps,
particularly at the reduced light levels. The dimmer control,
which has used successfully in many other applications,
see Section 4, utilizes a auto-transformer, which varies the
input voltage (110 VAC) to the high voltage power supply used with
these viewing lights. As shown in Figure 2-1, two separate dim-
ming or brightness controls,,which now incorporate the separate
on-off controls, are provided on the side surface since the
imagery to be stereoviewed might be of different densities and the
stereo fusing is easier done when the imagery is presented on a
comparable image brightness basis.
Each dimming control will vary the intensity of its light source
without noticeable flicker at any level of intensity. The two inde-
pendent controls are conveniently located at the rear sides of the

light table within comfortable reach of the operator from the front,
yet not interfering with any of the viewing or mensuration functions.
The light table operates on a nominal 115 volt, 50-60 cps supply,
and will use approximately ZOO watts of power. The light table is
equipped with a 3-wire power cord, not less than six feet long,
terminated at one end with a "Deflex" Safety Power Connector
, or its equivalent. The other end is termin-
ated within the light table and is securely mounted to the frame of
the light table. The third (ground) conductor in the power cord is
grounded to the metal frame of the light table.
2.3 MENSURATION MECHANISM
The proposed mensuration mechanism is the simplest and most
economical means of providing X and Y measurements in digital
readout form, of the photo imagery,with an accuracy of *0.001"/
inch. As shown in Figure 3-1, digital readout, as a 4-digit num-
ber, is provided for each axis. This provides quick and easy
accuracy of ?0.001" per inch, with means for reading or inter-
polating to 0.0001". The lead screws will be ground to micro-
meter accuracy. An anti-backlash gear train provides the re-
quired speed-up to the digital counter, so that the digital pre-
sentation corresponds precisely with the distance traveled. The
X (horizontal) counter is located on the extreme left and the Y
(vertical) counter is located on the extreme right so as to still be
readable when longer film strips are used and yet not increase the
size of the light table.

2.4 MICROSCOPE MOUNT
Proposal No. SME-CG-58
5 March 1966
The microscope mount shown in Figure 2-1, can be used with
either the Model II Zoom 70 Stereoscope, the IModel
M-5 Stereomicroscope, or the new Stereoscope with its
various working distances and modes of operation.
In addition to supporting the Zoom 70 as a stereomicro-
scope and as a stereoscope, it will now have a third mode of
operation. This new mode utilizes the I rhomboid
assembly as presented in the I drawing furnished us.
Instead of the old ring for supporting the zoom pod, we
will now use the ring from the versatile stereoscope.
This ring must be turned upside-down in order to clear the
25X1 rhomboid assembly. It is our understanding that
this ring can be removed and replaced after the support mechan-
ism is turned over so that no additional effort is involved.
25X1
MI
The microscope support bar is provided with an adjustable slide
having three inches of travel in the Y direction. This slide will
be corrosion resistant and incorporates a clamp screw to lock it
in the desired position. The slide is designed so as to nest into
the power supply housing area when pushed towards the rear so
as not to increase the depth of the light source. The slide will
utilize anti-friction bearings so as to provide friction free heavy
duty linear motion with minimum twist, minimum shake and minimum
play.
A separate microscope/stereoscope mounting post is proposed for
the Zoom 70 so as to provide a higher degree of perpendicularity
of optical axis to the Scanning Stage. This mounting post would have
a large diameter base extending as high as possible within the working
distances of this instrument.

2.5 SCANNING STAGE
Proposal No. SME-CG-58
5 March 1966
The scanning stage as shown in Figure 2-1 has the film clamped to it
in the same manner as previously proposed, with the micro-
scope stage clips. In this revised design we now have a 15" wide by
9" deep glass stage supported in a metal frame. This stage is secured
to the frame through preloaded ball bushings so that no play or clear-
ances can affect the resolution of the imagery while viewing under a
high power magnification. The X positioning mechanism is supported
off the Y mechanism so that it moves in the Y direction with the stage.
The Y positioning mechanism control wheel is fixed and remains sta-
tionary with the basic light source. With this ,larger movable glass
stage the entire light source can be utilized for viewing throughout the
specified ranges of travel. Finger holds are provided in the position-
ing controls for rapid rotation so as to provide a fast slew capability.
The final adjustments are considered to be made by small angular ad-
justments of the control to the exact point required.

has been prepared by]
in response
to the requirement for providing the additional features of a Scanning
Stage and Mensuration to the Twin Light Source Stereoscope Light
Table' Proposal No. SME-CG-55). is partic-
ularly well qualified in the engineering technologies which are
essential for successful design, development and fabrication of the
required light table. Of particular value in the proposed program
is extensive experience in developing equipment for
image interpretation systems with mensuration, such as the
Multi-Sensor Viewer. Based upon this background, can offer
assurance of repeating of high-quality picture illumination and
reliable dimming control in addition to the new-added features.
1.2 BRIEF DESCRIPTION
The Light Table with Mensuration Scanning Stage, as shown in
Figure 2-1, is a table top unit which presents approach
to efficiently adding the capabilities of a Scanning Stage to the Twin
Light Source Stereoscope Light Table. This scanning stage has
extremely smooth movement, even when fast slewing, so that the
imagery does not jump when viewing through a microscope. The
mensuration capability, provided for each axis, has an accuracy of
O. 001"/inch.

FILM VIEWER DESCRIPTION
2.1 OVERALL CONFIGURATION
The Light Table with Mensuration Scanning Stage, as shown in
Figure 2-1, is a kil)le top unit which provides the divided viewing
surface directly in front of the operator. The viewing controls are
conveniently located on the rear inclined top surface, so that all
controls are within easy reach of the operator with no obstruction
of the viewing surface or interruption of the viewing operation, when
actuating the controls. The viewing surface is split about its front
to rear centerline, so that each 5-inch x 6-inch viewing area becomes
independent light sources when the partition is removed. This per-
mits stereo viewing with differing densities or with differing scales.
The scanning stage is fastened to the sides of the main casting, so
as to. not inconvenience the operator by further projections toward
him. As shown in Figure 2-1, the X and y positioning controls are
conveniently located on the sides for easy actuation by the operator -
while looking through the microscope. The X positioning control
is on the left and the Y is on the right. The stage is positioned by
precision lead screws having 10 threads per inch, so that ten revolu-
tions of the handwheel will result in one inchof travel. This pitch
lead screw provides the best combination of slew speed and sensitivity
in that 3. 6 ? of rotation corresponds to 0.001" of travel.

2.2 ILLUMINATION SYSTEM
2. a. i. Light Sources
Proposal No. SME-CG-55
27 September 1965
The light sources are the same; two 5-inch wide x 6-inch deep viewing
surfaces directly adjacent to each other for ideal usage as a larger
single viewing surface. The two light sources are high intensity,
cold cathode grids. These grids are interchangeable, are not potted
or encapsulated, and are easily replaced by relatively unskilled
personnel using a minimum of the common hand tools. Although
the cost of these high intensity, cold cathode grids is considerably
greater than that of the standard fluorescent tubes, the advantages
obtained result in far greater overall value. These advantages are:
?
Service life of 10,000 hours.
No deterioration from frequent on-off cycling.
Minimum height can be realized for table top
utilization
Simpler wiring and circuitry, therefore much
greater reliability and down time .
Assurance that illumination is always even and
uniform since perimeter grid can be made closer.
With individual tubes there is no guarantee that
they will age uniformly; they deteriorate more
rapidly with on-off operation and when a tube
is replaced, it will be much brighter than the
others.

Proposal No. SME-CG-55
27 September 1965
As before, the light sources will be sufficiently diffused such that
the variation in intensity will not exceed ?5% as the working surface
is scanned along a line which is perpendicular to the light grids. The
temperature of the light table will not rise more than 15? F after
extended use (6 - 8 hours). The air vents will be baffled to prevent
light from shining into the operator's eyes or the eyes of anyone
in proximity.
The total viewing area is approximately 10" wide x 6" deep with
the diffuser being a single piece of opal plastic. As shown in
Figure Z-1, the light baffle, which separates the two grids and
prevents light from spilling between the two grid areas, i s easily
removable. The upper, or working, surface of the glass on the
scanning stage protrudes above the surrounding area by at least
1/16". The metal surface immediately surrounding the scanning
stage glass has four holes, two on each side, for the insertion of
the Zoom 70 spring stage clips.
2. 2..2
Viewing Light Controls
Another advantage available with the proposed cold cathode grid
viewing light sources is the highly reliable dimming control, which
can vary the brightness over the entire range without any flickering,
as usually occurs with standard fluorescent lamps, particularly at
the reduced light levels. The dimmer control, which has
used successfully in many other applications, see Section 4, utilizes
a auto-transformer, which varies the input voltage (110 VAC)
to the high voltage power supply used with these viewing lights.
As shown in Figure 2-1, two separate dimming or brightness controls,
as well as two separate on-off controls, are provided on the top
surface, since the imagery to be stereoviewed might be of different
densities and the stereo fusing is easier done when the imagery is
presented on a comparable image brightness basis.

27 September 1965
Each dimming control will vary the intensity of its light source without
noticeable flicker at any level of intensity. The two independent
controls are conveniently located at the rear of the light table within
comfortable reach of the operator from the front, yet not interfering
with any of the viewing functions. The separate on-off switches will
incorporate built-in lamps, which indicate when the light source has
been turned on. The switch button will be suitably engraved.
The light table operates on a nominal 115 volt, 50-60 cps supply,
and will use approximately 200 watts of power. The light table is
equipped with a 3-wire power cord, not less than six feet long,
terminated at one end with a "Deflex" Safety Power Connector (made
or its equivalent. The other end is terminated within
the light table and is securely mounted to the frame of the light
table. The third (ground) conductor in the power cord is grounded
to the metal frame of the light table.
2.3 MENSURATION MECHANISM
The proposed mensuration mechanism is the simplest and most
economical means of providing X and Y measurements of the photo
imagery with an accuracy of 0.001"/inch. As shown in Figure 2-1,
two precision dial indicators are utilized to always provide a readily
available and convenient readout of scanning stage position. To
avoid increasing the size of the light table and inconveniencing the
operator, the Y motion has been limited' to 3" of travel whereas 4"
of travel is provided in the X direction. The precision quality dial
indicators shown are standard proven mechanical instruments,
which have a good history of reliable and accurate performance with
minimum maintenance requirements.

2.4 MICROSCOPE MOUNT
Proposal No. SME-CG-55
27 September 1965
The microscope mount shown in Figure 2-1, can be used with either the
'Model II Zoom 70 Stereoscope, the !Model M-5 Stereo-
microscope, or by use of the clamp type adapter -- any similar
stereoscope or microscope of approximately the same size and weight,
as before.

ALTERNATE SCANNING STAGE DESIGN
3.1 OVERALL CONFIGURATION
An alternate scanning stage design is presented in Figure 3-1. This
provides the capability of having 4" of travel in the Y direction as
against the 3" travel previously shown. The dimensions of this alter-
nate configuration are 20-1/2" deep X 18-4/4" wide X 6" high. Essen-
tially, it provides minimum width at the expense of depth. As shown
in Figure 3-1, the film is now maintained stationary and the stereo-
scope or microscope is precisely transported over the film. It is
considered that this small travel of the microscope while scanning
will not be too uncomfortable for the operator. The microscope is
supported on precision dovetail slides for added stability. The 10
threads/inch lead screws used for positioning have much greater
a.ccuTacy. The positioning controls have been slightly relocated,
but still provide the same capability of ease of positioning while
looking through the microscope.
3.2 MENSURATION MECHANISM
With this alternate configuration, an alternate mensuration mechan-
ism is indicated. As shown in Figure 3-1, digital readout, as a
4-digit number, is provided for each axis. This provides quicker
and easier readout to the nearest thousandth of an inch. The lead
screws will be ground to an accuracy of better than ?0.0002"/inch,
so that one revolution will always transport the microscope pre-
cisely 1.0000 ?0.0002". An anti-backlash gear train provides an
exact 10:1 speed-up to the digital counter, so that one revolution
of the lead screw results in 10 revolutions of the counter. Each
revolution of the counter turns the "thousandth's" wheel for a
. 3-1

complete revolution and increases the "tens" wheel by 1 digit.
Therefore, 10 revolutions of the counter shaft changes the read-
out by 100 thousandths. The gears will be precision 3 gearing,
having a maximum tooth-to-tooth composite error of 0.0002"
and a total composite error of 0.00025". With 72 pitch gears
having a tooth-to-tooth spacing of 0.0139", the variation of
?0.0002" represents an angular variation or error of 0.0139/
0.0002 = 1/70. Since one revolution (3600) of the counter is
equivalent to 10 thousandths of an inch, the variation obtained
is 0. 010/70 = 0. 00014"; less than the pitch error.

RELEVANT EXPERIENCE
4.1 INTRODUCTION
extensive experience in the development of Image Inter-
pretation Film Viewers is a valuable asset in the development of
this direct viewing Light Table. In addition to the development of
compact cameras, stabilized mounts and film processing units for
airborne use, is continually engaged in the development
of precision equipment for the ground based operations of film
viewing and interpretation. The exacting demands of this latter
technology have imposed on engineers a stringent discipline
which leads to a critical appraisal of design concepts and the deft
execution of the actual design and construction. Of particular signifi-
cance in developing image interpretation equipment is
recent and current experience in the development of the Image Inter-
pretation Cell (IIC), wherein close field association with the various
Air Force tactiCal reconnaissance commands has acquainted us with
the "working level" P.1. requirements. The IIC was designed and
fabricated by for the RADC under Air Force Contract
for the prototype, and ror the pro-
duction systems. The IIC is a completely self-contained., deployable,
image interpretation system for the generation of forward echelon,
accurate intelligence data in the form of Flash and Immediate Photo
Interpretation Reports. The IIC was subjected to a series of mech-
anical and environmental tests which verified the soundness of the
product design and its capability for sustained operation in the
military environment. Examples of Image Interpretation
Film Viewer developments which are closely related to this proposed
program are discussed below.

4.2 MULTI-SENSOR VIEWER
The Multi-Sensor Viewer,
Proposal No. SME-CG-55
27 September 1965
P/N 1080A1, was developed by
for
integrated interpretation and analysis of multi-sensor data. ?
The MSV, see Figure 4-1, provides simultaneous direct viewing of
70rnm to 9-1/2 inch film at four stations. Hard copy print repro-
duction under normal room light conditions and full mensuration
capability, with digital readout, is provided at all four film stations.
Stereo viewing with zoom magnification is provided at the two
horizontal stations with a slack loop drive on the first station
(panoramic channel) for points up to 72" apart. In addition, the
TTR projection viewer located on top, enables viewing of 70 X
100 mm film chips at 4X magnification for comparison viewing.
The operator may display at random any one of 100 chips contained
in a removable magazine. Ten extra chip magazines, each con-
taining 100 chip holders are stored within the MSV.

Illumination for the light table consists of three fluorescent tubes
with a translucent diffusion panel as a viewing surface. A 300 watt
projection type filament lamp, used with double condensing lenses
and an f /4.5 projection lens, provides illumination for imaging the
negative on the 9" x 9" viewing screen.
The print processor is motor driven and has a removable roller
assembly. Processing solutions (developer and stabilizer) are in
32 oz. flexible plastic bottles (for durability and light weight).
The purpose of the F-512 Viewer/Printer is to provide a convenient
means for--
(a) viewing 5 inch wide aerial negatives in roll form
on an illuminated light table.
(b) viewing a 2X enlarged image of each 4-1/2" by
4-1/2" negative, or similar section of a panoramic
negative, on a 9" x 9" rear projection screen.
(c) obtaining 9" x 9" positive enlargements of each
negative (or stereo pairs) on photographic paper
under subdued room light (no darkroom necessary).
4.4 IIC LIGHT TABLE
The Image Interpretation Cell Light Table served as a detailed inter-
pretation station to supplement the activities of the MSV and to provide
a working area for detailed interpretation and analysis. As shown in
Figure 4-3, it provides direct or stereoscopic viewing of positive or
negative film from 70mm to 9-1/2" in width and up to 1000 ft. capacity
rolls. The film is secured to the light table by'a vacuum hold down

system for mensuration or viewing under magnification. A carriage
and rails are provided to provide movement in the X and Y direction
of: the stereoscopes over the 10" x 39" viewing surface.
The Light Source - two argon-mercury grids of serpentine pattern
embedded in an optically clear, elastomer matrix for protection
against mechanical shock and humidity damage. This source will
provide diffused "cold" light of a maximum intensity of at least 1200
it. -lamberts at 70?F. "Cold" light refers to the low heat output of
the grid, a 15?F temperature rise over a 4 hour period. Uniform
aiia.;.Lon is accomplished by mounting the plastic diffuser at the
correct distance from the grids.
The film under observaeion can be held securely to the glass top if
desired. The top contains front and rear vacuum grooves which are
connected to silicone rubber vacuum manifold tubes connecting to the
outer edges of the glass top.
When 9-1/2" wide film is being used, the vacuum is applied to both
manifolds. For 70mrn and 5" wide film, the vacuum is only applied
to the front groove, which is covered by the film.
The film reels are held between brackets attached to the table in either
the left or r:.eglit T-rails. Each table is supplied with two sets of Reel
Brackets, each set consisting of one crank and one idler bracket. The
machine will accommodate single reels of any size from 70mm to
9-1/2" in width up to 1,000 feet capacity. The brackets are equipped
with drag brakes, cam operated spindle retractors and full ball bearing
suspension in all instances. Segmented nylon rollers at each end of the
table provide scratch-free film support. The cranks provide a pivoting
detent of the handle so that it can be rotated out of the way when not in
use.

QUALITY ASSURANCE AND RELIABILITY
6.1 INTRODUCTION
The Quality Assurance and Reliability functions at are
integrated within the Systems Management and Engineering
Department and the Quality Control Department. These Depart-
ments report to the General Manager. The degree of responsibility
exercised by each with regard to the coverage in these areas de-
pends on the nature of the program. In the case of a developmental
type of program where the quantities of equipments are very limited,
the primary responsibility for both Quality Assurance and Reliability
rests with the Engineering Department. As the quantities increase
and the requirements and methods become more firmly established,
the responsibility shifts to the Quality Control Department. This
section describes the proposed procedure which will be used as a
guide in the case of this Twin Light Stereoscope Light Table.
The Quality Control program at now in effect on existing
projects is in compliance with MIL-Q-9858. The procedures em-
ployed are under the surveillance of the resident Air Force inspector.
plant is the home office for the
now in
effect on existing projects is in compliance with MIL-R-27542. The
eliability organization is shown in Figure 6-1, and its
functions are noted in Figure 6-2.

6.3.1 Design Review
Proposal No. SME-CG-55
27 September 1965
When preliminary design has been con laci:ort, basic objectives are
to detect design errors, misapplicati.e of pi..rts, ease of mainten-
ance and the role of human factors.
6.3.2 Use of Preferred Parts
Parts which have been used successfully on previous applications
under similar conditions of use will be preferred. Parts for which
adequate reliability data or history is not available will be avoided.
6.3.3 Human Engineering
The design will be examined to assure that panel layout, visual
displays, location and selection of controls are compatible to the
physical capabilities and limitations of the human operator.
6. 3. 4 Usage Factors
Knowledge gained from previous experience with the Multi-Sensor
Viewer development, the operation and field use of the equipment
will be invaluable in designing into the film viewer those consider-
ations which will forestall the incidence of failures due to the lack
of this knowledge.
6.3.5 Failure Reporting and Analysis
When failures occur during check-out operations, a failure report
such as shown in Figure 6-3 is required. The reliability engineer
will assure that the cause of the failure is ascertained and that
suitable corrective action is taken.
