Scanning holography and two-dimensional image processing by acousto-optic two-pupil synthesis

Abstract

An implementation of an acousto-optic heterodyning image processor was reported earlier [ Opt. Lett.4, 317 ( 1979)]. However, details of that report are limited only to the confirmation of the basic principle of operation. In this paper, we present and emphasize the mathematical structure of the processor. We also compare this processor with other kinds of scanning and nonscanning processors. The analysis is then extended to the defocused case, where the optical transfer function is derived. A potential application of this in scanning holography is discussed.
