It is possible at this point to draw several conclusions regarding the use of a
polarizer to penetrate atmospheric haze. Under suitable conditions the polarizer
produces a substantial improvement in the contrast, edge sharpness and detail which
is observed in a long range oblique photograph. The improvement is observed both
in color'and in black-and-white photography using a No. 12 haze filter.
The improvement in contrast is most dramatic when the following conditions
1. The atmosphere is clear and the dominant source of
haze is Rayleigh or molecular scatter. While a
polarizer is helpful on a haze day, the improvement
is slight. Thus, a polarizer is primarily effective
in making good photography much better.
2. The camera is pointed perpendicular to the sun and
the sun elevation is low. However, a substantial im-
provement also occurs when the sun angle is high in the
case of a long range oblique.
3. Using a haze filter and polarizer the contrast enhance-
ment becomes greater as the path length is increased.
This is because Rayleigh scattering events are less
frequent in the longer wavelength end of the optical
spectrum. Thus, Rayleigh haze is significant only when
looking through a long atmospheric path.
Another observation which I believe will be of interest is that the resolution
appears to be substantially improved by the use of a polarizer. Tnis occurs because
the contrast of the optical image has been raised above the threshold of the particular
lens-film combination. Thus, small detail which would otherwise be lost in the film
gradularity becomes visible, not because the resolution is improved, but because
the contrast is improved.
In short, it has art now been demonstrated that a properly oriented polarizer, in-
telligently used, will substantially increase the range, contrast, and resolution of an
aerial photography. At this time the question of whether a polarizer should be used on a
particular mission can only be answered on an individual basis.
I am enclosing a Program outline which would result in a capability to plan
future missions and design future systems on a sound engineering basis. While the pro-

gram is large, a reduction in its scope would seriously limit its usefulness to future
system designers and mission planners. I feel that the results obtained recently more
than justify a program of this magnitude.

COMPARISON OF PHOTOGRAPHY
ACQUIRED
WITH AND WITHOUT POLARIZING FILTERS
The photography resulting from the test runs was examined with the considera-
tion that the tests were conducted to determine if polarizers can improve the extrac-
tion of intelligence information from photography by photo interpreters. Generally
speaking all of the photography taken with the combination of a polarizer and filter had
greater edge sharpness, contrast and color rendition, where color was used, than any
other photography acquired in the tests. Identification of small objects such as air-
craft and vehicles, especially in upper half of the format was definitely enhanced by
the imagery acquired with the polarizer.
Recognizing that in most cases photo interpreters do not work with the original
negative contact duplicate positives as well as the original negatives of the black-and-
white photography were examined for information content. Each set of D.P. Is, com-
prised of photography acquired with and without the polarizer, was reproduced with a
single exposure setting and identical chemistry. The results showed that although "
there was a resolution loss the polarized imagery retained the superior edge sharp-
ness and contrast.
Comparison of the,sets of photography was somewhat hampered because only
one camera was available. Minor time variations in photo acquisition and scene dis-
placement in the format occurred in each set compared. Two cameras mounted side
by side permitting simultaneous exposures would provide a more precise comparison.
The polarized imagery from each set of photography was examined first for selection
of targets for comments. The polarized imagery was then compared to the other
imagery. The slant range to the imagery in the center of the format is approximately
15 NM in all cases. Thus the cross format scale at the center is approximately 1:85,000.
The results of the comparisons are as follows:
a) Roll 7, run 5, color imagery was acquired through a polarizer and
2E filter. The sun is approximately 90? to the camera look angle at a high elevation.
Run 5 is compared to the nonpolarized imagery obtained through 2E and 0. 6 ND filters

on run 6, roll 7.
B-52 and C-135 aircraft at Kirtland AFB present no identification problems in
the polarized imagery. On the nonpolarized imagery these aircraft are difficult to
impossible to identify by type. The aircraft are located in the lower part of the upper
third of the format. In this portion of the format edges on the polarized imagery are
well defined, contrast is good and color rendition is good. By comparison the edges
on the nonpolarized imagery are fuzzy, contrast is low and color rendition is poor.
The Sandia weapons storage site is imaged at the extreme edge of the oblique
on the nonpolarized imagery and near the edge on the polarized imagery. Tunnel en-
trances into the mountain and buildings near them are easily defined and measurable
on the polarized imagery. The nonpolarized imagery reveals that the tunnel entrances
are barely discernible and the nearby buildings are poorly defined. Mensuration would
be extremely difficult.
Comparison of rows of vehicles parked in and around an oval track located in the
upper third of the format was made. The polarized imagery, by virtue of superior
contrast and color rendition, permitted a more definitive vehicle count although count-
ing the vehicles was difficult.
Examination of the lower half of the format revealed that ventilators and stacks
on building roofs were easily discernible on the polarized imagery while on the non-
polarized imagery many of these were not resolved. The same was true of windows
in buildings.
b) Roll 7, run 7, color imagery was acquired through a polarizer. The
sun is approximately 900 to the camera look angle at a high elevation. Run 7 is com-
pared to the nonpolarized imagery obtained through a 0. 6 ND filter on run 8, roll 7.
The B-52 and C-135 aircraft in this case are again easily identifiable on the
polarized imagery. Additionally engine pods are recognizable on the aircraft. The
aircraft are difficult to identify by type on the nonpolarized imagery and the engine
pods are not recognizable. The aircraft are imaged in the middle portion of the for-
mat. Hangars and fueling trucks also imaged in this section of the format are notable.
Vents on the hangar roofs are clearly visible on the polarized imagery but cannot be

seen on the nonpolarized imagery. The fueling trucks are readily identifiable on the
polarized imagery and cannot be identified on the other imagery. In this portion of
the format edge sharpness and contrast on the polarized imagery is good. Color ren-
dition is poor. Edge sharpness on the nonpolarized photography is fair, contrast and
color rendition is poor.
The weapons storage site is imaged on the upper third of the format in both
types of photography. Again the tunnel entrances are easily identifiable on the
polarized imagery. The edges of buildings are sharp and windows in the headquarters
building are discernible. Mensuration of structures and tunnel entrances could be
accomplished with relative ease. On the nonpolarized imagery the tunnel entrances
are identifiable. The windows in the headquarters building cannot be discerned.
Edges of buildings and tunnel entrances are soft which would complicate pointing for
mensuration purposes.
A railroad marshaling yard is imaged near the middle of the lower half of the
format. A rail car count is easily performed and some of the cars can be identified
by type on the polarized imagery. Vehicle counts in nearby parking lots can be made
without difficulty. An accurate rail car count could not be performed on the nonpolar-
ized imagery and identification by type was virtually impossible. Vehicle counts in
the adjacent parking lots were difficult to impracticable to accomplish. Here edge
sharpness and contrast were good on the polarized imagery while color rendition was
poor. The edges and contrast on the nonpolarized imagery were fair and color rendi-
tion poor.
c) Roll 10, run 2, color imagery was acquired through polarizer and
2E filter. The sun is approximately 90' to the camera look angle at a low elevation.
Run 2 is compared to the nonpolarized imagery obtained through 2E and 0. 6 ND fil-
ters on run 4, roll 10.
The rail cars in the marshaling yard in the center of Albuquerque can be counted
on the polarized imagery with relative ease but cannot be identified by type. A car
count on the nonpolarized photography is difficult and of questionable accuracy. The
rail cars cannot be typed. The marshaling yard imagery is located in the middle

of the format. Contrast and color rendition are good to fair on the polarized photog-
raphy and the edge sharpness is fair to poor. The unpolarized imagery is poor in color
rendition and edge sharpness, contrast is fair to poor.
A tank farm and parking lot are imaged in the upper section of the middle third
of the format. The tank diameters and heights can be readily measured on the polar-
ized photography. The edges of the tanks that are in shadow on the nonpolarized pho-
tography are extremely difficult to define thus hampering any attempts at mensuration.
The vehicles in the nearby parking lot can be accurately counted on the polarized pho-
tography whereas this cannot be accomplished on the nonpolarized imagery.
In the lower third of the format roof ventilators, stacks and windows in buildings
are very difficult to define on the polarized imagery. 'Except for a few isolated cases
it is not possible to define ventilators, stacks and windows in the nonpolarized pho-
tography.
The scene at the top portion of the format is a flat desert beyond mountains.
Several roads, a power trace and what is probably a small building are visible in the
polarized imagery. The power trace is very indistinct to not visible in some areas'
on the nonpolarized imagery. The roads are barely recognizable and the probable
structure is not identifiable.
d) Roll 8-y run 3, black-and-white imagery was acquired through a
polarizer and a No. 12 filter. The sun is approximately 90? to the camera look angle
at a high elevation. Run 3 is compared to the nonpolarized imagery obtained through
No. 12 and 0. 6 ND filters on run 4, roll 8.
Kirtland AFB is visible on the photography in the upper half of the format.
Examination of the polarized original negative reveals that B-52 and C-135 aircraft
are easily identifiable by type and that engine pods are clearly visible. Vents on the
hangar roofs are easy to see and fueling trucks are identifiable. Contrast and edge
sharpness are good. The duplicate positive from the polarized negative permit iden-
tification of the B-52 and C-135 aircraft and engine pods are distinguishable. The
fueling trucks can be identified and the hangar roof vents are visible. Edge sharpness
remains good but the contrast is somewhat reduced. The nonpolarized original nega-

tive permits identification of the B-52 and C-135 aircraft but only some engine pods
are identifiable. The fueling trucks can be seen. A few of the hangar roof vents are
1. last. Edges are soft and contrast is fair. The duplicate positive from the nonpolarized
original negative permits identification of B-52 and C-135 aircraft. Engine pods and
fueling trucks are not identifiable. Some vents on the hangar roof can be seen. Edges
are quite soft and contrast is fair.
The Sandia weapons storage site is imaged on the upper third of the format. The
polarized original negative has good contrast and permits easy identification of tunnel
entrances and defines building edges well. Windows in the headquarters building can
be seen. On the duplicate positive edge definition is slightly reduced and the windows
in the headquarters building are lost. The tunnel entrances on the nonpolarized origi-
nal imagery are difficult to see and building edges are fuzzy. The headquarters build-
ing is barely discernible among the trees. Contrast is fair to poor. The nonpolarized
duplicate positive permits approximately the same level of information extraction ex-
cept that the headquarters building cannot be defined.
Examination of the lower third of the format on the polarized imagery reveals
that roof vents, stacks and windows can be readily seen on the original negative.
These items are visible on the duplicate positive. These same images are marginally
identifiable on the nonpolarized original negative and, with a few exceptions, lost on
the duplicate positive.
e) Roll 12, run 2, black-and-white imagery was acquired through a
polarizer and a No. 12 filter. The sun is approximately 900 to the camera look angle
at a low elevation. Run 2 is compared to the nonpolarized imagery obtained through
No. 12 and 0. 6 ND filters on run 3, roll 12.
The rolling stock in the marshaling yard in the center of Albuquerque can be
easily counted and some of the rail cars identified by type on the polarized original
negative. The scene is slightly above format center. Edge sharpness is fair and
contrast is good. The,car count is difficult on the polarized duplicate positive and
identification by type is not practicable. Edge sharpness and contrast are considered
fair. The nonpolarized original negative permits the same level of identification as

the polarized duplicate positive. Edge sharpness is fair and contrast is fair to poor.
A rail car count on the duplicate positive is difficult to impracticable.
Roof vents, stacks and building windows imaged on the lower third of the format
are seen without difficulty in both the polarized original negative and the duplicate
positive. Edge sharpness and contrast is good. Many of the building windows and
some vents and stacks are lost on the nonpolarized original negative and duplicate
positive. 'Edge sharpness and contrast are considered fair.
Mensuration of tanks in a tank farm imaged at the bottom of the upper third of
the format can be accomplished on the polarized original negative and duplicate posi-
tive with confidence. Tank edges in the shadows on negative and positive nonpolarized
photography are difficult to define. Vehicles lined up in rows in a nearby parking lot
can be counted with accuracy on the negative and positive polarized imagery. This
cannot be accomplished on the nonpolarized imagery.
