THEORETICAL AND EXPERIMENTAL INVESTIGATION OF PHOTOCHROMIC MEMORY TECHNIQUES AND DEVICES

Abstract

Results are presented on the basic sensitivity and resolution capabilities of photochromic materials. Photochromic coatings are similar to photographic emulsions in that they exhibit a change in transmission with excitation by light of the proper spectral distribution. Photochromic coatings differ, however, in two respects: they do not require a development process and they exhibit a reversal of state (return to the first state) when illuminated by light of a second spectral distribution. In this reversal of state, photochromic coatings are similar, superficially at least, to magnetic coatings. Temperature and fatigue characteristics are also discussed, with special attention given the stability of the colored state with temperature. Chemical data is presented on the light sensitive materials, the solvents, and the coatings.
