abstract

For an optical correlator system, information is encoded in four dimensions (spatially, bits per pixel and time). This paper describes an optical correlator system that was built around 8-bit, 256 x 256 spatial light modulators capable of operating at four kilohertz frame rates. The full data throughput of the optical processor is not realized due to limitations with the correlation plane detector and post processor. However, continuous operation at nearly a kilohertz was demonstrated.
