Determining the parameters of an obturator shutter in an AFU-75 satellite camera
Abstract
A method is derived for determining the shutter parameters of an AFU-75 satellite camera. These parameters include the radius of shutter wing rotation, the distance from the shutter rotational axis to the wing slit, the distance from the shutter rotational axis to the photograph surface, and others. Testing of the method has shown that it yields parameter values accurate enough to calculate exposure times with an accuracy of about 0.0001 second.
