Abstract

Holographic optical correlators using incoherent light have been developed for pattern recognition. In this paper we show how multiplicity of holographic filters can be incorporated into such correlators for recognizing several patterns simultaneously. Our computer simulation and experimental results reveal that sixteen patterns can be recognized with one composite holographic filter, giving a sharp correlation peak with good peak to background ratio.
