Abstract
A liquid crystal spatial light modulator (SLM) was used as a programmable reticle in an optical system. The function of the SLM system was to perform a spatial frequency analysis on an incoherent input scene, by means of successive correlations over a set of spatial basis functions. Because of physical modulator characteristics, the basis function set available from the reticle was a set of DC-biased square waves, rather than the sinusoids used in a usual Fourier analysis. This led to the “even pulse train transform” being performed on the input images. Experimental examples of this frequency analysis are given for two sample scenes, a square aperture and a double slit aperture.
