Abstract

A construction of the optoelectronic system with binary power spectrum is presented for target recognition. In the beginning, the minimum average correlation energy method is used to yield the reference function. Then, the multi-level quantized reference function is implemented at the input plane of the liquid crystal spatial light modulator in the joint transform correlator . Numerical result is presented.
