摘　　要：介绍了一种用于航天立体摄影的大视场准远心光学系统，其光组结构形式为复杂化的双高斯型．主要光学参量为f’=23．3mm；2ω=37．8°；F／数=F／5；MTF均值达到0．8时，对应的空间分辨率大于36lp／mm；光谱适应范围为0．5～0．75／μm．在实验室进行了模拟推扫，合成了三维立体图像．模拟试验结果表明该光学系统满足航天立体摄影的要求．A wide field of view telecentric optical system that is used to obtain space three-dimension photogrammetry was introduced. The structure of optical system is complicated double Gauss telecentric lens. The capital optical parameters are f＇ =23.3 mm, 2ω=37.8°,F/number=F/5 and spectrum range 0. 5-0. 75 μm. Imaging resolution was over 36 lp/mm when MTF reached 0.8. Simulant experiment and synthetical three-dimension photogrammetry show that this optical system can suffice require of space three-dimension photogrammetry.
