Paper Abstract

The input image phase encoding method is utilized for identification of random binary phase masks (RBPM) and their separated fragments with a joint transform correlator (JTC). Equations for a joint power spectrum of a reference RBPM and its separated fragment and for a fragment's autocorrelation function produced in a JTC are obtained. Dependences between separated mask's fragment parameters and autocorrelation output signals are determined. Equations for autocorrelation peaks coordinates definition at a JTC output plane are found. Computer simulations of a mask's fragments autocorrelation functions are carried out. Influence of a mask and a fragments dimensions on output autocorrelation and sidelobe peaks is studied on a base of obtained results. Algorithm for realization of a code identification by a JTC with a phase-encoded input is proposed
