Abstract

An optimization technique for the optical correlation detection process is proposed. The noise correlation output is suppressed by prewhitening its spectrum. Since the optimization operates on the noise instead of the signal spectrum, the system tolerance for size and orientation variation is not severely affected. Experimental illustrations are also presented.
