Optical Correlator for Image Motion Compensation in the Focal Plane of a Satellite Camera

Abstract The paper presents the concept of a system for the compensation of the image motion in the focal plane of a satellite camera. The image motion is compensated by corresponding shift of the image sensor, controlled through direct visual feedback. The system includes an auxiliary image sensor and an optical correlator for the high precision measurement of the motion of a dark and fast moving focal plane image. Questions of system realisation are considered, expected performances are estimated on base of the optical correlator hardware model testing
