【摘要】：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 such as large amount of calculation and great influence of plane shape error in the alignment of large aperture space optical system based on wavefront or star map, a method based on discrete array light source is proposed to align the space optical system. The design, detection and calibration method of discrete array light source are presented, and the alignment detection light path is designed. Taking a RC telescope in research as an object, a detecting light path for fast alignment of primary and secondary mirrors is designed by using discrete array light source to generate reference light. Under the condition that the design parameters of the optical system are known, the functional relationship between the position information of primary and secondary mirror and the distribution information of the point sequence diagram is established according to the point sequence diagram in the image plane. The simulation platform is established by using optical design software and mathematical calculation tools, and the simulation of primary and secondary mirror is carried out. Simulation results show that the use of discrete array light sources can effectively reduce the amount of calculation, reduce the effect of surface error and stray light, improve the alignment efficiency, and have a high accuracy.
