Space-bandwidth product and crosstalk of spatial filtering methods for performing binary logic optically

The optical implementation of binary logic is desirable since many bits can be processed in parallel. Spatial filtering is an optical method that can be used for performing binary logic operations optically. In this paper we quantitatively investigate the space-bandwidth product and the crosstalk as measures of quality for several variations of this spatial filtering method. The quality parameters depend on the encoding scheme used for translating the binary information into optics.
