Research on the applications of miniature optical pattern recognition system

A miniature optical pattern recognition (OPR) system is proposed in this paper. We use a multiple channel optical correlator to perform real-time image processing, such as dynamic multiple objects recognition, nonlinear operation of fusion of correlation output, and compression and reconstruction of infrared fingerprint images. The preliminary experimental results show that a two-dimensional optical correlator based on binary optics makes the OPR system to tend to practice.
