Abstract

In this paper we evaluate the expressions of the image field of two encoded-hole plates which are placed according to a specific desire. For the unique image field distribution, we proposed an incoherent correlation recognition with the main-peak-enhancement technique. Theoretical analysis and the computer analogue on the correlation showed the recognition improved the discrimination of correlation evidently as well as the resistance to the noise of the optical system. Finally, we obtained the conclusion that the main peak of correlation increased as the numbers of the encoded holes K increased, with the maintaining of its sidelobes.
