Abstract : An optical image correlator using a spatial light modulator (SLM) for reference image recording and correlation readout has been demonstrated. The reference image correlation filters are recorded in a volume holographic optical element using wavelength multiplexing. Auto and cross correlations between similar and dissimilar images were compared to determine the image discrimination characteristics of the optical correlator.
