Abstract

An architecture for an optical processor for recognizing and locating objects in cluttered two-dimensional scenes without prior knowledge of the position, scale, or in-plane rotation has been developed. The system involves Fourier transforms, a computer generated hologram for coordinate transformation, a technique for optical phase extraction, optical correlators, and spatial light modulators (SLMs). Experiments have been conducted to verify parts of the design.
