Paper Abstract

In contrast to conventional sampling, implicit sampling permits the unique representation of a bounded bandlimited bipolar function in terms of a set of positive real numbers. This is important for noncoherent optical processing as a means of handling bipolar input functions without suffering the non-coherent light buildup and associated loss of contrast in the output plane of the processor usually encountered in other approaches. We will describe recent results of applying implicit sampling in optical correlation and Fourier transformation that illustrate the utility of implicit sampling in optical computing.
