Paper Abstract

There has been a growing interest recently in the use of Phase-Only Filters (POFs) and Binary Phase-Only Filters (BPOFs) for optical pattern recognition. While BPOFs can be obtained by binarizing the phase of the classical matched filters, one wonders if the filter performance can be improved by allowing more phase levels. This paper provides a theoretical analysis of the increase in output Signal-to-Noise Ratio (SNR) as the number of phase levels is increased.
