摘    要:离轴三反光学系统具有成像质量高、可实现大视场、无遮拦等优点,但其装调难度大,镜面支撑结构质量大。为解决这些问题,基于三级像差理论,研究一种主镜、三镜可集成一体化的大视场离轴三反光学系统,并以焦距为1 200 mm,F数为12,视场为101的光学系统为例进行了验证设计。结果表明:调制传递函数接近衍射极限,视场内平均波像差RMS值为/55,最大波像差RMS值为/22。设计结果显示,光学系统装调自由度由12个减少到6个,可使光机系统可得到简化,实现了主三镜一体化设计。

关 键 词:光学设计   离轴三反光学系统   像差理论   一体化设计

Abstract:Off-axis three-mirror system(OTMS) has the advantage of high image quality, large field of view and non-obscuration. But drawbacks also exist, such as the alignment difficulty, cost and large optomechanical weight. In order to solve these problems, the design of a novel OTMS was necessary. In this design, the primary mirror and tertiary mirror can be integrated on a single substrate based on third-order aberration theory. An example which has a focal length of 1 200 mm,F-number of 12 and field of view of 101 was given. The mean WFE rms was /55, and the maximum WFE rms was /22. The result of this design shows that the number of alignment freedoms was reduced from 12 to 6, the weight of the mirror support assembly also can be lighter.
Keywords:optical design  off-axis three-mirror system  aberration theory  integration design
