An infrared-bi-color Schottky-barrier infrared CCD image sensor for precise thermal image

An infrared-bi-color image sensor was developed with barrier height controlled Schottky-barrier photo diode array for precise temperature image. Vertically arranged low and high barrier height diode pixels in horizontally stripe order were arranged by using a selective area ion implantation technique. Conventional monochromatic infrared image sensors have only measured the temperature for a black body object. The infrared-bi-color image sensor can precisely obtain the temperature image for gray bodies, whose emissivity values are unknown.<
