Abstract

A new method for implementing optically real-time wavelet-matched filtering is proposed by using nonlinear four-wave mixing in photorefractive media. In comparison with conventional matched filtering, the proposed method is able to give higher discrimination ability. Experimental results for optical character recognition are presented.
