Abstract

Because of their suitability to two-level spatial light modulators, binary phase-only synthetic discriminant function (BPOSDF) filters are of much interest in optical pattern recognition. In this paper, we will compare three BPOSDF filter design methods using a common database. The three methods are Relaxation Algorithm, Successive Forcing Algorithm and a Phase Grating Approach recently introduced by us. The figures of merit used for this comparison include: Fisher Ratio, Recognition Rate, and Light Efficiency.
