摘要
为实现多传感器光轴校准并达到小型化轻量化的设计要求,将目视瞄准镜作为校轴光学基准,采用共用摄远型物镜组,并利用在立方棱镜斜面镀制光谱分光膜,实现高精度目视瞄准镜与激光接收的共光路系统设计。该目视瞄准镜放大倍率为7×、视场为5°、出瞳直径为Φ3.7mm、出瞳距离不小于20mm;激光接收系统视场为1mrad、接收口径为Φ50mm,设计结果满足指标要求。
To realize the correction of the optical axis and satisfy the requirement for miniaturization and lightweight,a laser/visual sighting telescope system was designed,which had the common path with laser receiving and visual collimator.By means of shared telephoto objective and coating beam-splitting film on inclined plane of the block prism,the system was applied to optic-electronic observatory,with visual correction of optic axis and laser receiving.The magnification of the visual sighting telescope is 7×,the field of view(FOV)is 5°,the exit pupil diameter is Φ3.7mm,and the exit pupil distance is not less than 20 mm.The laser receiving system has the FOV of 1mrad and the entrance pupil diameter of Φ50mm.The designed results meet the index requirments.
