Abstract

This paper proposes another application for the joint transform correlator. The principle of the correlator could be used for determination of a relative translation of two speckle patterns. An optical processor based on this architecture is designed. Such processor could be a part of an optical system for a noncontact measurement of object translations, rotations or normal vibrations. This paper is devoted to operation simulation of the optical processor. Firstly, the theoretical description of the processor is made. Then follows a depiction of the preparation of input data for the simulation analysis. The detailed results of the simulation can be found in the last part ofthe paper
