Abstract
An optically fixed photorefractive correlator is presented, where two-center nonvolatile holographic recording proposed by Buse et al is employed to write and fix the matched filer in doubly doped LiNbO3 crystals. This correlator shows good correlation characteristics and insensitivity to recording beam during readout. It can be used in those requiring stability not requiring modified for a long time, and refreshed optically when new information need be registered.
