A real-time large-capacity rapid-scanning optical correlator utilizing a rotating grating concept is described. We have shown that the proposed scanning (OSC) capable of processing memories with rapid spectrum scanning. With implementation closed-circuit TV system, OSC system can be applied in real-world situations. also experimentally tested overall correlation sensitivity due to scanning, object orientation, scale changes, and tilting grating. Several experimental results obtained this are included.
