【摘要】 CCD星敏感器是无人飞机等航空航天器姿态控制的关键设备,其工作谱段很宽,跨可见光至近红外光光谱,且对系统的体积有特殊的要求,从而可满足飞行器的小空间体积的要求。针对一实际用于无人飞机上的系统的要求(焦距为60～100mm,F/1.3～F/2,谱段范围为0.48～0.85μm,视场为80°～100°),提出了使用折衍混合的新型光学系统,在较宽谱段内消除了色差,并校正了其它像差。从设计结果可以看出,系统可满足最终的使用要求。更多还原

【Abstract】 CCD star tracker is the key equipment of the pose control of space probe such as robot bomb,it works at the broad wavelengths,from the visible wave to the near infrared wave,and the volume has the peculiar request as to satisfy the small space of the whole aerocraft.Based on the actual system(focal length is 60～100mm,the F number is 1.3～2 and the field of view is 8°～12°,wave is from 0.48μm～0.85μm),a new hybrid optical system is put forward,it reduces the secondary color aberration at the broad wavelengths and emends other image errors.The design results show that the system meets the final useful claim.更多还原
