Paper Abstract

An optical correlator using a spatial light modulator (SLM) in the filter plane of half the spatial resolution of an SLM in the input plane is analyzed and evaluated. Reducing the resolution of the filter affected the image used to make the filter by adding a shifted copy of the image to the original. Reducing the resolution of the filter by half resulted in a decrease in storage space and a potential increase in speed by a factor of four. Autocorrelation experiments performed were comparable to those performed at full resolution. In addition, the rotation sensitivity of the filters reduced in resolution were less than that of filters using full resolution.
