Abstract

Design of a compact correlator, using a low power He-Ne laser for obtaining optical phase conjugation in BaTiO₃ crystal, is presented in this paper. The angle between the reference and dc beam is optimized to reduce the dimension of the correlator. The overall size of the correlator is reduced further by using separate read beam.
