Abstract

Replication in the output plane of an optical correlator, due to pixelation of the Fourier plane filter, can lead to false correlation signals. This paper suggests randomization of the pixel positions of the Fourier plane filter as a solution, and demonstrates its effectiveness through computational simulations and optical correlation experiments using a custom made SLM.
