RESEARCH AND DEVELOPMENT PROGRAM ON AN ELECTROCHEMICAL ADAPTIVE SYSTEM FOR PATTERN RECOGNITION.
Abstract
EXCITATION OF PASSIVE IRON SURFACE BY HEATING: A hypothesis is proposed that the passive iron film illuminated in 50-60% HNO3 is being disrupted by the intense heating at the surface occasioned from the ruby laser and that results similar to energy densities of 50,000 watts/sq cm over a period of about 0.5 mec would be obtained over a broad range of incident wavelengths. The hope is that with a strength vs. duration excitiation curve there will result data for designing a scanning image system capable of converting image patterns into parallel travelling patterns of electrochemical excitation in a manner reminiscent of the human eye and retina. SEARCH FOR RESONANCES IN THE PASSIVE SURFACE LAYER ON IRON IN NITRIC ACID: Molecular or other resonances are sought by using subthreshold illumination. A system of optical filters and/or monochromator with various inherent light sources will be used as well as a light chopper operating in the range of 1 to 100 cps, and a synchronous or narrow-band-tuned voltage detector circuit.
