【摘要】：针对紫外通信接收光学系统的特点和发展趋势,在共轴三反光学系统的基础上,提出了一种离轴三反紫外光学系统的设计方法,利用ZEMAX软件进行优化。设计出了一个焦距为998.192mm、视场角不小于4°、F数为4的离轴三反光学系统。在50lp/mm空间频率处传函达到0.4以上,接近衍射极限,全视场弥散斑控制在5μm以内,同时克服了共轴三反存在的中心遮挡问题,提高了系统的像质。该系统设计满足相应技术要求,对紫外通信系统的成功研制具有重要作用和意义。
[Abstract]:In view of the characteristics and development trend of ultraviolet communication receiving optical system, a design method of off-axis triple reverse ultraviolet optical system is proposed on the basis of coaxial triple reverse optical system, which is optimized by ZEMAX software. An off-axis three-mirror optical system with a focal length of 998.19mm and an angle of view of not less than 4 掳F is designed. At the spatial frequency of 50lp/mm, the transmission function is more than 0.4, which is close to the diffraction limit, and the total field of view dispersion is controlled within 5 渭 m. At the same time, it overcomes the central occlusion problem and improves the image quality of the system. The design of the system meets the corresponding technical requirements, and has important role and significance for the successful development of ultraviolet communication system.
