摘要
文章介绍了一种带读出电路的1024元短波MCT红外等角度扫描成像系统.叙述了该扫描成像系统的构成,在图像处理中应注意的两个主要问题:探测器非均匀性校正和行列图像信号的修正.该扫描成像系统采用国产1024元线列MCT(碲镉汞)焦平面器件,自行研制的同轴透射式光学系统和一维等角度并行扫描方式,扫描效率超过88%,扫描半周期为5秒,每帧像素为1024×1600.该系统在野外获得了较为理想的红外图像.
Abstract
It is presented in this paper a scanning and imaging system which consist of 1024-element MCT line short wavelength IRFPA with reading electrocircuit made in china. It is presented the composing of the imaging system and some key question of the imaging system during picture disposing: 1) nonuniformity correction;2) Correction of lines and rows. With same axial transmission optics and a 1-D equality angle scanner and 1024×1600 pixels per frame, the scan efficiency of the sensor is over 88% and the half periods of scanner is 5 seconds. A better IRFPA picture has been obtained by use of this imaging system.
