CAMERA INFORMATION FOR KEYHOLE MISSION 9009
This publication presents the technical information necessary for the
reduction of quantitative data obtained from photography of Mission 9009.
It is planned that a similar publication will be prepared for each future
mission. This photography involves the use of three cameras: amain
camera, a port horizon camera, and a starboard horizon camera. Thr. ee
illustrations (Figures 1, 2, and 3) are included as pictorial supplements
to the information in the text. The dimensions shown on Figure 3 may be
used for film-shrinkage studies. The sign convention used is that in which
the nadir offset will be provided.
1.
Operational Focal Lengths
A.
Main lens
23.989 inches
B.
Port horizon lens
89.30 mm
C.
Starboard horizon lens
90.35 mm
Definition: "Operational focal length" is defined as the distance
from the main lens nodal point to the film plane as measured on
the lens bench, and the data reduced for a vacuum condition.
(Operational focal length is equivalent focal length corrected fo1-
environment. )
2. Lens Distortion
A. Main lens -- at 3? radial, plus 0.012 mm.
B. Port horizon lens -- at 10? radial, .000 mm; at 20` radial,
plus .009 mm.
C. Starboard horizon lens -- at 10? radial, .000 mm; at 20? ~-a-
dial, plus .003 mm.
3. Depression Angle of Horizon Cameras
A. Port horizon camera 14? 52'
B. Starboard horizon camera 15? 00`

4. Image Motion Compensation
Forward motion compensation is accomplished mechanically
during the scan by causing the lens system to move opposite to the
direction of flight during the scan and returning for the next cycle.
The camera drive mechanism is such that there is a fixed me-
chanical relationship between the forward motion compensation, the
cycling rate, and the scanning rate.
The relationship between the forward motion compensation and
the cycling rate has been established fora 10% overlap condition at
the nadir.
Camera cycle time 2.402 seconds

Scan rate (constant) 71.628 inches/second
IMC rate (parallel to
flight direction) in
inches /second = .787 Cos e
where e is the displacement (expressed in degrees of arc) normal to
the flight direction.
For example, e will be zero degrees at the nadir and 35 ? at either
end of the format.
