OPTICAL DATA PROCESSOR FOR ARTEMIS,

Abstract

This report describes the theory and operation of an optical cross-correlator developed for application in the ARTEMIS program. The first part of the report discusses the theory of coherent optical systems and derives the basic operations that such systems can perform. A discussion of the fundamental limitations of optical processors, such as effects of nonuniform film motion in recording, partial coherence, film thickness variations, etc., is included. Particular emphasis is placed on the concept of mixed integration to some extent and because it appears that this type of processing is desirable for the data to be collected in the ARTEMIS program. A discussion of frequency-plane processing is also included, even though the processor built for ARTEMIS does not use this mode, because future processors are likely to be some variation of a frequency-plane processor. The later sections of this report describe the optical correlator that was built and include instructions for aligning and operating this processor.
