Abstract

Cross talk is observed in a photorefractive bridge mutually pumped phase conjugator during the transient time of photorefractive grating formation and is utilized to construct a moving-object correlator. The correlation of various input images has been demonstrated and compared with calculated results. The device is currently capable of a resolution of approximately 4 to 6 lines/mm.
