Paper Abstract

A high speed optical correlator is presented in this paper. It is a joint transform correlator using a BSO photorefractive crystal in the Fourier plane. The performance of the system such a rotation and scale robustness are presented for fingerprint recognition. To demonstrate the interest of such an optical processor, a comparison with numerical systems is presented. Besides, we will also show that the evolution of correlators is quite compatible with the evolution of numerical processors.
