Thin-Film Acousto-Optic Surface Wave Interactions and Devices.

Abstract

We have studied the diffraction pattern and its electronic scanning of the resultant acoustic beam from plane and stepped array transducers. The results show that for a limited angular scan the diffraction patterns and their phase and frequency scanning may be described, to a large degree, in terms of the phased-and frequency-scanning array antenna theory with some modifications. Some applications with both types of array transducers are described. In particular, the stepped array transducer is shown to have several immediate applications in connection with wideband guided-light beam deflection.
