| 摘 要： | 为了描述失调状态下反射光学系统在整个像平面中的波像差分布特性，从而对反射光学系统进行有效的装调，对偏心和倾斜影响下的几种反射光学系统的三阶彗差和三阶像散进行了研究。首先，对失调光学系统三阶波像差的矢量形式进行了推导。然后，对失调状态下经典Cassegrain系统、Ritchey-Chrtien系统和三反射镜消像散系统三阶彗差和三阶像散的分布情况进行了分析，并且对两反射和三反射系统的装调进行了简要的讨论。使用Zernike多项式对视场中各个位置的波像差进行拟合，分离出三阶彗差和三阶像散并进行了全视场显示。理论分析与实际拟合结果一致，说明结论是正确的。

| Abstract: | In order to characterize wavefront aberration behavior of misaligned reflective optical systems over the entire image plane,thereby realize effective alignment to reflective optical systems,the third order coma and third order astigmatism of several reflective optical systems with tilt and decentration were studied.Firstly,the vector form of the third order wavefront aberration of misaligned optical system was deduced.Then,the distribution characteristics of third order coma and third order astigmatism of misaligned classical Cassegrain systems,Ritchey-Chrétien systems and three mirror astigmatism systems in the image plane were analyzed.Finally,the alignment of two mirror and three mirror optical systems was briefly discussed.Moreover,Zernike polynominals were used to fit wavefront aberrations of grid sampling points in the view of field.Third order coma and third order astigmatism were separated and displayed over the whole field of view.Theorectical analysis and practical fitting results were similar,which shows that conclusions are correct. |
