Abstract
In this work, the analysis of an optical - digital system based on the Fourier transform hologram architecture is presented. We are interested in the diffractive effects in the Spatial Light Modulators as the sampling in the Fourier plane and the diffraction produced by squircle-geometry apertures of pixels. Also, a mathematical analysis is done in terms of the fringes visibility of the filters. Simulations and experimental results of the method are shown.
