基于离散阵列光源的空间光学系统对准

为了解决基于波前或星点图对准大口径空间光学系统时计算量大、面形误差影响大等问题, 提出了一种基于离散阵列光源对准空间光学系统的方法.给出了离散阵列光源的设计、检测和标定方法, 并以此为基础设计了对准检测光路.以某在研RC望远镜为对象, 用离散阵列光源产生参考光, 设计了一个用于快速对准主次镜的检测光路.在光学系统设计参数已知的情况下, 根据像平面上的点列图, 建立了主次镜位置信息和点列图分布信息的函数关系.利用光学设计软件和数学计算工具建立仿真平台, 并进行了主次镜的仿真验证.仿真结果表明, 使用离散阵列光源可以有效减少计算量, 降低面形误差和杂散光的影响, 提高对准效率, 并且具有较高的计算准确度.

Abstract

In order to solve the problems of aligning the space optics by wavefront errors or stellar image, the large amount of calculation and the great influence of surface shape errors, and so on, a discrete light source is proposed. And based it on, an alignment and measurement optical system is designed. The optical system is designed to measure and align a Ritchey Chretien telescope quickly by using the discrete light source as the reference ray. When the parameters of the optical system have been known, the relationship could be established exactly between the alignment errors and the spot diagram on the image plane. A simulation flat form is developed by using of the optical design software and the mathematics calculation tool. Then, the algorithm is proved in the simulation flat form. The simulation results show that using the discrete light source could reduce the amount of calculation, decrease the effects of the mirror errors and the stray light and have the precise calculation result.
