RESEARCH AND DEVELOPMENT ON INFRARED DETECTOR

Abstract

AN IR detector which combines microwave concepts with infrared sensing elements was investigated. A photosensitive semiconductor is coincidently energized by a microwave electromagnetic field, and the infrared radiation to be sensed. Since the device employs no dc bias, associated IF noise is eliminated. Further, the sensing element is placed in a high microwave cavity which provides amplification of the order of Q/Pi without deterioration of the S/N. (Author)
