Synthetical method of Lohmann's and Lee Wai-hon's matched filters in optical pattern recognition

Abstract

From the purpose of accuracy and convenience, a new filter function is used to make optical matched filters in practical optical pattern recognition system by adopting Lohmann's and Lee Wai-hon's holography. These filters can reduce the half-width ofcorrelation peak, improve the SNR and discrimination performance in correlation plane. PRINCIPLE
