The volume of information we handle is markedly increasing as a result of the change from text data to still and moving image files. In this paper, we propose and describe fabrication of a much higher speed search engine for image and video data using a holographic optical disc system. Preliminary correlation experiments using the holographic optical disc setup show an excellent performance as indicated by high correlation peaks and low error rates at a multiplexing pitch of 10 μm, and a rotational speed of 300 rpm. It is clear that the processing speed of our optical holographic calculation is markedly higher than the conventional digital signal processing architecture. This system can also be applied to various search engine systems.
