发展紫外全景成像仪已成为空间大气遥感领域的迫切需求。提出一种紫外全景成像仪光学设计思路，利用桶形畸变和光阑像差改善像面照度的均匀性，根据应用要求采用折反式结构，设计了一个中心波长在360 nm，带宽为10 nm，视场为360°×(70.9°～73.3°)，焦距为5 mm，相对孔径为13.3的紫外全景成像仪光学系统。在奈奎斯特频率38.5 lp/mm处，调制传递函数大于0.72，点列图半径的均方根(RMS)值小于1/2 pixel，80%的能量集中在一个像素内，f-θ畸变小于0.05%，像面照度均匀性达到89%，各项指标均满足设计要求。此系统结构紧凑，适合空间大气遥感应用。分析结果表明，该紫外全景成像仪光学设计思路是可行的，可推广到其他波段应用，对全景成像仪的设计具有指导意义。

Space atmosphere remote sensing urgently requires ultraviolet (UV) panoramic imager. An optical design method of UV panoramic imagers is proposed. The uniformity of image illumination is improved by using barrel distortion and pupil aberration. Based on the requirements of application, an optical system of UV panoramic imagers is designed. The central wavelength is 360 nm, the bandwidth is 10 nm, the field of view is 360°×(70.9°～73.3°), the focal length is 5 mm, and the relative aperture is 13.3. The modulation transfer function (MTF) is more than 0.72 at the Nyquist spatial frequency of 38.5 lp/mm. The root-mean-square (RMS) radius of spot diagram is less than half of the pixel. 80% of the energy is enclosed in a pixel, the f-θ distortion is less than 0.05%, and the uniformity of image illumination is 89%. The design requirements are satisfied. The configuration of this system is compact and is suitable for the application in space atmosphere remote sensing. It is indicated that the optical design idea of UV panoramic imager is feasible, and the design method can be used in other wavelength ranges, which is instructional for designing panoramic imagers.
