The advantage of this type camera, besides its unique space
configuration, is. that it can cover any angle of scan desirable by
the simple programming of the film metering drive system. Since
the entire camera rotates, representing a relatively large inertia,
the rotational speed can be. made quite smooth and accurate, thereby
permitting a precision velocity command to the film metering drive
system. Also, the power consumption for this type of camera is
relatively low because of the constant speed drive of the majority
of the camera mass.
This type of camera has been developed by Fairchild and it has
proven to be a basically sound, reliable piece of equipment for
photographic reconnaissance. Techniques have been proven which
permits reliable film handling in spite of the fact that intermittent
film motion demands slack loop control to avoid acceleration and
deceleration of the film spools. The constantly rotating spools are
mandatory in a high acuity rotating panoramic camera to avoid dynamic
reaction that would degrade the photographic image. By using slack
loops, the masses to be accelerated and decelerated are minor and do
not contribute to any degradation of resolution.

As with all panoramic cameras, the slit width determines the
exposure time and in this case the slit width in conjunction with
the lens angular velocity produces the overall exposure time.
Film handling is accomplished by intermittent metering of fresh
film into the focal plane arc during either the capped return stroke
of the lens drive or during the portion of the cycle that the lens is
outside the format. Loop control is also utilized to permit continu-
ous rotating of the relatively large spools of film.
Image motion compensation can be achieved readily an this type
of camera by providing a fixed cam near the axis of rotation of the
lens and allowing the lens to move along its axis of rotation while
scanning to provide the necessary cosine function for proper 1W.

panoramic camera fabricated by Fairchild. The anticipated resolution
for this lens in the configuration shown is. well above 50 lines/Mm

Film handling is accomplished in this type of camera by conventional
means since it consists of a flat focal plane with the film stationary
during exposure. Image motion compensation can be achieved on'this type
of camera by moving the lens prism assembly or lens mirror assembly, as
the case may be, laterally during its scan. Figure 5 shows an attempt

shown in figure 4, for smaller coverage angles. As shown in figures
4, b, and 7 this technique is feasible.by providing a dual camera
installation. Additional advantages of the dual camera installation
may be realized from the standpoint of reliability and reduction in
film spool sizes. The advantage of using the mirror where applicable
is that the prism has limited resolution capabilities and is also
considerably more expensive and heavier for a given system.

As with the traveling. lens panoramic, the prism can be replaced
by a mirror for a limited angle of coverage. Two (2) such configurations
are shown in figures 6 and 7. Since the lens is stationary in this type
of panoramic camera the optical path can be folded for convenience as
shown in figure 6, or the lens-film optical path can be simple as shown
in figure 7. The nodding mirror arrangement is somewhat different from
the rotating prism in that the nodding mirror is bi-directional with the
film stationary during the mirror-return stroke. Again only the slit
area becomes over exposed between format frames.
Slack loops are used in both configurations of the nodding mirror
approach to permit intermittent, relatively high speed scanning past a
fixed slit. Again this type of camera image motion compensation may be
accomplished by rocking the focal plane slit and film through the proper
function during scan.

Exposure Factors
In determining the required exposures for the detail reconnais-
sance camera, several factors must be taken into consideration.
Among the most important are scene brightness and brightness ratio
at the camera, spectral distribution of image forming light, film
speed, film spectral sensitivity, film quality capability, shutter
speed, aperture, film processing, time of day, month and cloud cover.
For convenience, each major factor can be considered separately
prior to the discussion of the interdependence of these factors.
Brightness
Scene brightness on the ground is calculated from standard
equations and from experimental data. * Scene brightness
includes both direct illumination and sky light in the
horizontal plane. Based on the beat data available assumed

c. Spectral Distribution'of'Image.Forming Light'
At very low and decreasing solar altitudes the spectrum
of the direct illumination shifts rapidly towards the
red while sky light is still predominately in the blue
region. These factors allow the choice of several tech-
niques for obtaining photographic information at low solar
altitudes if such becomes an operation requirement.
d. Film Characteristics
1. Spectral Sensitivities
All films that can be favorably considered for use in
the proposed cameras on the basis of speed, quality,.
and availability have completely adequate spectral
sensitivity characteristics.
b. Scene Brightness Ratio;,
Quality and Speed
At any given time in the state-of-the-art of silver halide
sensitization, image quality capability varies as some inverse function
of film speed. This fact immediately presents 'a balance between film
quality and speed that must be made in the choice-of a suitable
emulsion since it is necessary to obtain both high quality images and'
i.he longest possible operational day.

Supersonic Considerations
It should be pointed out that a photographic reconnaissance system from a
supersonic vehicle must consider the effects of shock wave and boundary layer
on both photographic quality and photogrammetric quality. The consideration
is divided into these two catagories mainly because of the two types of cameras
aboard the aircraft.
In general past experimentation has shown very small effects on photographic
quality and therefore should not be of great concern in the proposed mission.
The photogx'ammetric effect is still under evaluation and no specific data is
available at this time.

The Rapidyne Shutter, representing the most advanced design
in high efficiency high speed between-the-lens shutters will
be utilized. This basic shutter has been a standard part of
the T-11 and KC-1 cameras'and has a proven reliability record
well in excess of 20,000.cycles. The shutter will be tripped
by means of an electronic timer and will have continuously
variable shutter speeds from 1/50 to 1/700 of a second total
open time.

Provision can be made for either digital binary recording of
pertinent flight data, on the recording of data instruments
through a system of internal lighting and recording lenses.
Fiducial markers accurately locating the principle point of
the lens will be recorded with both artificial and natural
