Optical Power Spectral Analysis for Machine-Readable Factor Maps.

Abstract

A preliminary investigation of the application of Optical Power Spectral Analysis (OPSA) approaches to machine-readable factor maps for terrain information systems is presented. The objective is to offer a more compact, simpler, and cheaper data base storage and retrieval system that would be available by all digital technology. In the basic concept of the systems, OPSA is used to decode data from reduced factor maps that have been encoded by spatial frequency and direction of optical gratings. (Author)
