提出了一种将全景成像系统应用到大气临边探测的光学系统设计方案。首先考虑到特殊的工作波段以及创新性应用，根据应用技术指标，在传统全景环形透镜的基础上，结合探测器尺寸限制，精细调整四个球面的曲率半径，以便得到最佳光学传递函数。然后基于像差理论设计中继镜组系统，补偿全景环形透镜产生的像差，采用折射率 n以及阿贝常数ν不同的双分离的正负透镜组合，负透镜采用熔石英，正透镜采用氟化钙，从而使色差最小。最后运用CODE-V光学设计软件对系统进行优化，列出重要的公差参数，为后续加工装调提出要求。优化结果表明，光学系统在各个视场的光学传递函数均达到了0.7以上，各视场能量集中度为80％的弥散圆直径均小于11μm ，完全满足设计指标要求，也证明了将全景环形成像系统应用到紫外波段大气临边探测的方案是可行的。

In order to meet the requirements of imaging the surrounding 360°scene at one time without rotating the optical system and satisfy the UV limb detecting ,a panoramic imaging system was presented for atmospheric UV limb detection .First ,consid-ering the special working band and innovative application and proceeding from the basic principle of traditional panoramic annular lens ,the curvature radius of four spherical surfaces was adjusted ,combined with the detector size so that can get the best MTF . Then ,based on the aberration theory ,the relay lens system was designed to make up the aberration produced by panoramic an-nular lens .The separation of positive and negative lens combination with different refraction and Abbe number was used .The negative lens used fused silica ,while the positive lens used calcium fluoride ,so to correct the apochromatism .Finally ,the opti-cal system was optimized with CODE-V and the important tolerance parameters were listed ,so that the subsequent processing can be requested .The design results show that the diameter of 80% encircled energy of UV panoramic limb imaging system is below 11 μm ,which is smaller than the pixel size of CCD ,and the MTF value of the system is higher than 0.7@ 384 mm-1 over all fields .These data satisfy the requirements of the system and prove the feasibility of panoramic imaging system in atmospheric UV limb detection .
