Generation of the Wigner distribution function of two-dimensional signals by a parallel optical processor

Abstract
An optical system employing a reflective multipath scheme is implemented to generate a sectioned array of slices of the Wigner distribution function of a two-dimensional (2-D) signal. The optical system exhibits a parallel architecture, permitting the simultaneous generation and display of the N slices. Only a single transparency is needed, and no moving parts are required in the system. Experimental results on a few 2-D signals are presented.
