Paper Abstract

A novel 2D acousto-optic processor is introduced for a variety of 2D signal processing tasks that include ambiguity function and range-doppler processing, 2D raster format high resolution signal spectrum analysis, and triple correlation function generation. The optical design is based on an optically efficient, in-line, high stability, 2D interferometer using four acousto-optic devices. Via the simple technique of Bragg cell carrier offset adjustments, the processor can generate the desired interferometric output on a chosen spatial carrier that is required for bias removal and electronic post-processing. The processor has bandwidth limitations based on the type of Bragg cells used in the system.
