Abstract

Currently available spatial light modulators (SLMs) inevitably have an inactive area around each pixel and electrical or optical interaction between each pixel. We examine the effects these phenomena have when the SLM is used in an optical correlation system, both as an input device and as the reference function in the Fourier plane. The effects are quantified through the SNR and full width at half-maximum of the correlation plane signal through a computer simulation of the problem.
