Design of a LWIR Polarization Imaging System of Non-coaxial Type
摘要
Abstract
A complete technical proposal of LWIR polarization imaging is set up by the hardwaredevelopment, system correction and basical performances test: the introductions of hardware developmentare included of proposal selection, system composition, optical components, circuit principle. The sourceof nonuniformity response of four channels is analyzed, the fundamental of segmented linear correctionmethod is expounded, the result of correction of four infrared images is exhibited; NETD of single channelis measured about 60mK by experiments, the characteristic curve of MRTD is also drawn, central positiondeviation of system is about 4 pixels and error value of image registration is about 1.2 pixels which arecalculated on account of feature points. Images of polarization of a car are presented in this paper finally.关键词
