K. Konuma et al., AN INFRARED-BI-COLOR SCHOTTKY-BARRIER CCD IMAGE SENSOR FOR PRECISE THERMAL IMAGES, I.E.E.E. transactions on electron devices, 43(2), 1996, pp. 282-286
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 vertical
ly next to one another using a selective area ion implantation techniq
ue. Conventional monochrome infrared image sensor frequently give wron
g temperature images due to unreasonable emmissivity assumption. The i
nfrared-bi-color image sensor can obtain the temperature image precise
ly with regard to the emissivity of the object.
