Theoretical and experimental studies were performed in an effort to obtain an infrared image converter. The program was divided into three parts. Part I was concerned with the physics and material research in terms of the image conversion. Efforts were devoted to a study on the infrared photoconductive materials with high sensitivity in the near infrared region, and on the photoconductor which shows good photoconductive quenching properties. Some analysis of quenching mechanism was also done. Part II covered all kind of the solid state infrared image converters suitable to the infrared region. Effort of this interval efforts were concentrated to three problems the photoconductor quenching system, direct receiver of the infrared image, and the highly sensitive image converter system. Part III was another approach to the infrared image converter. Possibility of a new type photocathode suitable to the infrared region was studied. For this purpose p-Si-Al diode was taken up, and photoinduced Hot Electron Emission was experimentally observed. Some improvement of emission was obtained. Further, the analysis of Emission and some new proposals were described. Author
