摘要
概述了美国雷声公司与夜视和电子传感器委员会合作研发的第三代前视红外成像系统。与第二代热成像系统对比,为提高系统性能,该系统使用的主要新技术有:四视场双F数光学系统,引入了可变冷光阑、高分辨率(640×480和1 280×720)、双波段(中波和长波)焦平面探测器组件,内置可控温度参考源,高度集成化图像处理电路及配套系统仿真模块。对各项技术的优势、劣势、特点、应用难点作了简要的分析,最后讨论了现代红外系统的发展趋势。对国内红外成像系统的发展研究有实用价值。
The 3rd generation FLIR imaging system（3GD） of U.S.was summarized in this paper,which was developed corporately by the Raytheon and the Night Vision and Electronic Sensors Directorate（NVESD）.Comparing with the 2nd generation FLIR system,the advanced performance of 3GD was improved by applying many new technologies,such as four field of view optical system with dual F/ number,variable-aperture mechanism（VAM）,high resolution dual-band MW/LWIR FPAs in 640 ×480 and 1 280 ×720 formats,inner controllable thermoelectric thermal -reference,highly integrated image processing circuits and system-level simulation package.Via the public information of above technologies,their advantages,disadvantages,characteristics and application difficulties were analyzed.In the end,a brief discussion about the trend of development in modern infrared systems was given.It is useful for the development of Chinese infrared imaging system.
