Abstract
A system is described which consists of an acousto-optic Bragg cell, a Fourier transform lens, a vidicon detector, and a digital Fourier transform. This simple system has potential for processing wide bandwidth signals with significant time-bandwidth capability. Time delays were observed between two nearly identical signals of arbitrary wave shape and found to conform with the theory. Experimental results for three types of signals are presented: narrow pulse, FM chirp, and white noise; the results of which conform with the theory.
