Abstract

This paper describes focal plane arrays and thermovision systems for the middle infrared spectral region. The focal plane arrays are monolithic platinum silicide Schottky barrier infrared charge coupled devices. They have been designed for infrared imaging application in the 1 divided by 5.5 micrometers wavelength range. The array advantages include the high thermal and spatial resolution, the low noise readout, and a high uniformity of the sensitivity. Two types of infrared focal plane arrays are being discussed and experimental characteristics of the arrays are presented. High quality thermal images of real time can be produced by using this focal plane arrays. Different design configurations of FPA-modules for Sterling cooler are being considered and the features of the information processing in thermovision systems are presented. The thermovision system based on designed arrays with the lens f/1.1, 90 mm provides a temperature resolution: NETD equals 0.07 K.
