Universidad Auto´noma de BarcelonaDepartamento de Fi´sicaBellaterra, Barcelona 08193SpainE-mail: ifop1@cc.uab.esAbstract. Binary amplitude phase-only filters (BAPOFs) with high dis-crimination capability (DC) are presented. This enhancement is achievedby designing the region of support of the phase-only filters (POFs). Wepropose different approaches for maximizing the DC based on analyticalexpressions of the correlation function for real-valued input scenes.Computer simulation and experimental results are presented and dis-cussed. The experimental results coincide with the numerical analysisand demonstrate that the optimized BAPOFs obtained with this newtechnique produce high discrimination capability among several objects.For comparison, the optimization of the DC of the POF is formulated asan annealing problem.
