摘要
In this paper, we describe an image recognition system using a multi-channel optical correlator as the computational element and a volume holographic memory as a template database. By recording the holographic matched filters in the disk-type Ce:Fe:LiNbO3 crystal, the multi-channel optical correlator is constructed. The system performs the multi-category pattern recognition. Experimental results are presented and discussed.
