Abstract

The design of a digital-optical hybrid correlator is detailed. The design of the optical-Fourier-transform lens and the mechanical lens housing are detailed, as well as the video-rate fast-Fourier-transform digital signal-processing hardware and overall electronic control. Example results using several different filters and modulation techniques are described. © 2002 Society of Photo-Optical Instrumentation Engineers.

Item Type: Article
Additional Information: The paper reports a novel hybrid architecture that made a practical realization of dynamic optical pattern recognition possible. Subsequent commercialization has led to this technology being taken up by US MICOM, Redstone Arsenal, Huntsville, Alabama and the IIT, India and also exploited for 3-d display technology. This paper was invited for a special issue on Advances in Pattern Recognition, Techniques, Devices and Algorithms. Impact factor 0.952
