Abstract
Abstract The device for calibrating an image motion compensation aerial camera includes a pair of transparent scales formed on an enclosure having two light tight compartments, one for each scale. Each compartment contains a flash lamp which is energized at specifically spaced intervals determined by a one-shot multivibrator. During a test, the camera photographs a superposition of the two scales while the film is in motion. The amount of displacement between the photographed scales will indicate the velocity of the film.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A test device for use in measuring motion comprising a screen; a transparent main scale having a series of regularly spaced graduations formed on said screen; a transparent index scale formed on said screen in juxtaposition to said main scale; illumination means for passing light selectively through said scales upon energization of said illumination means; and timing means for energizing said illumination means such that light passes first through one of said scales and then through the other of said scales after a predetermined time delay.
Claim 2
Dependent Claim
86 words
A test device for use in measuring motion comprising a screen; a transparent main scale having a series of regularly spaced graduations formed on said screen; a transparent index scale formed on said screen in juxtaposition to said main scale; illumination means for passing light selectively through said scales upon energization of said illumination means; and timing means for energizing said illumination means such that light passes first through one of said scales and then through the other of said scales after a predetermined time delay.
Claim 3
Dependent Claim
37 words
The device according to claim 1 and wherein said index scale is a vernier-type scale having a series of graduations regularly spaced a distance which is different from the spacing of said graduation on said main scale.
Claim 4
Dependent Claim
42 words
The device according to claim 1 and wherein said illumination means includes two flash lamps each mounted in a different compartment; each said compartments having a different one of said scales forming a part thereof and being lighttight except for said scales.
Claim 5
Dependent Claim
37 words
The device according to claim 3 and wherein said index scale is a vernier-type scale having a series of graduations regularly spaced a distance which is different than the spacing of said graduations on said main scale.
Claim 6
Dependent Claim
90 words
The device according to claim 4 and wherein said timing means includes a pair of two input transmission gates and a monostable multivibrator having dual outputs connected to one of said two inputs of a different one of said transmission gates; the other of said inputs having means for connection to a source of power; the outputs of said gates being connected to a different one of said flash lamps, whereby said power is transmitted to said flash lamps via said gates when said multivibrator switches between the states thereof.
Claim 7
Dependent Claim
90 words
A test device comprising an opaque enclosure forming first and second compartments separated by an opaque partition; a main scale having regularly spaced transparent graduations formed on the walls of one of said compartments; a transparent index scale formed on the walls of the other of said compartments; said main scale and said index scale being in juxtaposition; illuminating means mounted in each said compartment for passing light selectively through said scales; and timing means for energizing said illuminating means for passing light through said scales at predetermined time intervals.
Claim 8
Dependent Claim
90 words
A test device comprising an opaque enclosure forming first and second compartments separated by an opaque partition; a main scale having regularly spaced transparent graduations formed on the walls of one of said compartments; a transparent index scale formed on the walls of the other of said compartments; said main scale and said index scale being in juxtaposition; illuminating means mounted in each said compartment for passing light selectively through said scales; and timing means for energizing said illuminating means for passing light through said scales at predetermined time intervals.
Claim 9
Dependent Claim
108 words
The device according to claim 6 and wherein said illuminating means includes a pair of flash lamps each mounted in a different one of said compartments; and said timing means includes a pair of two input transmission gates and a monostable muLtivibrator having dual outputs connected to one of the inputs of a different one of said transmission gates, the other of said inputs having means for connection to a source of power, the outputs of said gates being connected to a different one of said flash lamps, whereby said power is transmitted to said flash lamps via said gates when said multivibrator switches between the states thereof.
