ABSTRACT:
Prior art optical correlator systems can perform only translation or rotation. Moreover, images obtained from these prior art systems are blurred due to movements of the target. In the present optical correlator system, to compare symbols on a particular frame of a film with predefined symbols stored in a memory, a novel driving mechanism which can both translate and rotate the film is used. The driving mechanism includes a translation device which has a plurality of gears and rollers mounted in a platform within a housing which may be filled with a fluid having an index of refraction corresponding to that of the film. Motors are coupled to the housing for translating and rotating the driving mechanism so that selected symbols on the film may be compared both linearly and rotatively with predefined symbols. The driving mechanism may further be used as an image motion compensator for eliminating blurring caused by target movements.
