STUDY OF OPTICAL CORRELATION TECHNIQUES

Abstract

This document describes the basic methods by which electrical signals may be processed optically in ultrasonic delay lines. The description includes a summary of applicable physical optics theory, a comprehensive survey of known optical correlator systems, and a study of relevant restrictions on their operation. The physicial optics theory relates a generalized theory of light phase modulation to Raman-Nath diffraction, birefriengence, and the Fourier transform theory of lenses. The operations analysis include a computation of required light source strength and color bandwidth for adequate output signal-to-noise ratio, an intermodulation analysis and a summary of very high frequency restrictions on optical correlator systems. Finally, the optical systems surveyed are evsluated for use in a communications system. (Author)
