Abstract
An off-axis joint transform optical correlator architecture has been developed which utilizes a novel transmission type photoconductive organic polymer (POP) spatial light modulator. The arrangement allows the writing of `phase only' power spectra within the modulator. The off- axis architecture also allows the separation of the correlation signals from the unavoidable transmission of the writing beams through the modulator. Experimental results are presented during this communication.
