摘　　要：阐述了一种基于半球环形全景成像的紫外光学系统,从大视场的需求角度出发,设计了半球环形的全景成像光学系统,该系统可以实现对180°(H)×40°(V)空域实现成像覆盖的需求,系统适用于紫外成像,由于紫外波段系统材料较少,为减小系统像差,在第一片镜片采用了镀膜折返式方式进行设计,该设计不但实现了扩大系统视场接收范围的能力,还具备了镜片数量少的特点。所设计的系统体积小,覆盖面积广,成像质量高,有效的实现了环形大视场范围紫外图像获取。An ultraviolet optical system based on hemispherical circular panoramic imaging is described. From the perspective of the demand for large field of view, a circular imaging system is designed. The system can realize the demand of imaging coverage in 180°(H)×40°(V) airspace, which is suitable to ultraviolet imaging. Coated foldback design is used in the first lens in order to reduce aberration for less system material at ultraviolet, which expands the receiving range of the field of view and reduces the number of lens. The system has small volume, wide coverage area and high imaging quality, and the acquisition of ultraviolet image in circular large field of view is realized effectively.
