Simulation and Experimental Analysis of a Phase Conjugating Correlator

Abstract

The compact phase-conjugating correlator (PCC) devised by Duelli et al. [1] provides a compact and robust correlator design while being compact and insensitive to phase imperfections in the transform optics and spatial light modulator (SLM) commonly found in the more conventional Vander-Lugt correlator. This design has been allied to that of the hybrid concept described by Young et al. [2] to provide high-speed performance. The correlator is shown schematically in figure 1.
