Abstract

The effect of varying the illumination of the target scene on the performance of classical, binary, and fringe-adjusted joint-transform correlators is investigated. Simulation results show that the fringe-adjusted joint-transform correlator yields better correlation output than the classical or the binary joint-transform correlator under all illumination conditions of the target scene.
