Use of an optical data processing method for determination of the fraction of wavef ront reversal

A theoretical proposal is made of a new method for determination of the degree of reproduction in wavefront reversal (reversal fraction) based on filtering and optical processing. It is shown that the reversal fraction could be found by determining the convolution of the spatial Fourier spectra of the signal (incident) and reversed waves. An experimental setup is suggested. A brief discussion is given of the advantages and shortcomings of the proposed method, and a comparison is made with other methods.
