摘要

提出了一种对偏差敏感度较低的离轴三镜偏斜光学系统的设计方法。基于变换瞳孔坐标和结点像差理论，推导出光学参数与偏差之间的解析表达式，并建立了竣工性能评估模型。分析了镜面间距和离轴幅度值对偏差灵敏度的影响。利用本文提出的脱敏设计方法，可以设计出低灵敏度的离轴 TMA 光学系统。仿真实验表明，用我们的方法得到的离轴 TMA 光学系统的偏差灵敏度约为用标称性能优化方法得到的系统的 60%，建成后的性能约为标称性能优化方法的 1.49∼1.54 倍。

Desensitization design method of an off-axis three-mirror anastigmatic optical system based on the nodal aberration theory

A design method for an off-axis three-mirror anastigmatic optical system with low misalignment sensitivity is proposed. Based on the transformed pupil coordinate and nodal aberration theory, the analytical expressions between the optical parameters and misalignments are derived and an as-built performance evaluation model is established. The effects of mirror spacings and the off-axis magnitude value on the misalignment sensitivity are analyzed. With the desensitization design method proposed in this paper, a low-sensitivity off-axis TMA optical system can be designed. The simulation experiments show that, the misalignment sensitivity of the off-axis TMA optical system obtained by our method is approximately 60% that of the system obtained by nominal performance optimization method, and the as-built performance is about 1.49

\sim

1.54 times that of the nominal performance optimization method.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
