| 摘 要： | 折反射全景光学成像系统具有平面对称光学系统的成像特性，提出应用光焦度控制方程和超大视场光学系统六阶波像差理论来初步确定系统结构初始参数，在此结构基础上，应用Zemax软件对其进行设计和优化，得到了一款仅由1块偶次非球面反射镜和6块折射透镜组成的折反射全景光学成像系统。该系统工作在可见光波段，全视场角范围为12°～178°，F数为3.5，其像差得到了较理想校正，调制传递函数在空间频率40 lp/mm处均大于0.37，成像性能较好，满足实际应用要求。同时，对设计的系统进行了公差分析。

| Abstract: | The catadioptric panoramic optical imaging system has the imaging characteristics of the plane-symmetric optical system. Thus, the application of focal power governing equations and sixth-order wave aberration theory of ultra-large field of view optical system were proposed to preliminarily determine the initial parameters of system structure. Based on this structure, the Zemax software was applied to design and optimize, and a catadioptric panoramic optical imaging system consisting of one even aspherical mirror and six refractors was obtained. This designed system worked in the visible wave band. The angle range of the whole field of view is 12°~178°, and the F number is 3.5, thus its aberration is well corrected. The value of modulation transfer function is greater than 0.37 at the spatial frequency of 40 lp/mm, which has better imaging performance and meets the practical application requirements. At the same time, the tolerance analysis of the designed system is carried out. |
