Paper Abstract

After introducing the uncooled infrared imaging based on a novel bi-material cantilever, this article emphasize on an optical system of an IR imaging prototype. At first, we select the structure form of optical system. Our optical system prototype consists of an imaging optical component and an optical readout component. The optical readout component comes from 4f' optical system and has been made some improvement to reduce its size, weight and power consumption. Then we measure and analyze the parameters of the FPA and CCD, in order to determine the geometrical sizes and the aberration requirement for every lens. At last we report on the implement of the prototype. The imaging result is showed in this paper. Experimental results indicate that the NETD of this system is less than 200mK.
