RESEARCH TO DEVELOP TECHNIQUES FOR OPTICAL ANALOG MULTIPLICATION OF LARGE SCALE MATRICES.

Abstract

Research is described covering a series of investigations in which the applicability of several optical processes which take place in alkali halide crystals to the problem of optical analog multiplication of large scale matrices was determined. Experiments included in this program of research were (1) measurements to determine several low temperature properties of F and F' centers in KCl and KBr; (2) experiments on the formation, stability, and optical removal of complex centers in hydrogenated KCl; (3) investigations of the intensity dependence of room-temperature F center bleaching in hydrogenated KBr; (4) and semi-quantitative measurements of the optical thickness changes caused by roomtemperature ultraviolet generation of F centers in hydrogenated KBr. A discussion of several possible methods of performing optical multiplication, and a brief review of color centers in alkali halide crystals, are included. Also included are separate sections by different authors describing methods of preparing additively colored alkali halide crystals, and describing the development of a computer program to perform certain color center calculations.
