An Infrared-Bi-Color Image Sensor for Precise Thermal Images

Abstract

An infrared-bi-color image sensor was developed with a barrier height controlled Schottky-barrier photo diode array for precise temperature images. Low and high barrier height diode pixels are arranged vertically next to one another using a selective area ion implantation technique. The infrared-bi-color image sensor can obtain the temperature image precisely without the emissivity assumption.
