Abstract

We present what is to our knowledge the first quantitative analysis of the dual optimality that can be achieved in the all-optical two-port photorefractive joint-transform correlator. We determine the operating region where these ports have complementary performance: the first port performs well for non-Gaussian clutter noise, and the second port is optimal for additive Gaussian noise. Dual optimality is achieved without the performance compromise of the optimal trade-off filter approach.
