摘　　要：空间用三反离轴光学系统自20世纪70年代提出,从90年代开始在多个国家的卫星光学有效载荷中已经或计划得到应用并快速发展,技术基本成熟,领域涉及到对地观测、空间目标探测、天文观测、多光谱热成像、立体测绘等,但是普遍认为制造装调技术比较难。文章通过广泛调研国外三反离轴系统在空间的应用和发展现状,并按应用情况、系统参数和系统构型进行了分类比较,分析其发展趋势,为中国空间相机发展三反离轴光学系统提供借鉴。Space off- axis TMA system was put forward at last century, which was applied and developed on satellite payloads of many countries at 1990s. Technologies of Space off- axis TMA system were already ripe basically, and applications of it were referred as to several aspects, including observation to ground, exploration to space objects, astronomy observation, many spectrums imaging and three - dimensional mapping. But it was well known that the techniques of manufacture and assembly and test were quite difficult. Application and development situation of overseas space off- axis TMA system were presented on this paper, and according to the state of application, system performance and configuration, space off- axis TMA systems were classified and compared and the trend of development was analyzed, which was used for reference for off- axis TMA system used in space camera of China.
