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998.192 mm、视场角不小于4、F数为4的离轴三反光学系统。在50 lp/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5 m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: Through the analysis of the characteristics and development trend of the ultraviolet communication receiving optical system, a method of designing off-axial TMA ultraviolet communication receiving optical system is presented based on coaxial three-reflective optical system. The structural parameters of the system can be solved and optimized by ZEMAX. Then the off-axial three-mirror system with focal length of 998.192 mm, field of view of 4 and F-number of 4 is designed. The modulation transform function (MTF) of field of view is 0.4 at 50 lp/mm, and the full field diffusion plaque is controlled within 5 m. This system overcomes the central shielding problem which exists in coaxial TMA system, thus the image quality of the system is greatly improved. The system design meets the corresponding technical requirements, which is of great significance to successful development of ultraviolet communication system.
