Abstract

This paper extends the utilization possibilities of the joint transform correlator. The principle of the correlator can be used for determination of relative translation of two mutually displaced 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 deformations using the speckle decorrelation method. The paper presents computer simulation of the optical processor. In addition to basic theory of the processor the description of preparation of input data for the simulation analysis is mentioned. Both short description of the computing algorithm and some obtained results of the simulation are presented, too.
