摘要
空间引力波探测望远镜是引力波探测卫星的核心载荷之一,它同时对传输光束进行扩束和缩束。光程稳定性是望远镜的核心指标之一,其与望远镜结构稳定性密切相关。为了满足引力波探测任务对望远镜提出的超高光程稳定性和结构稳定性要求,必须对望远镜结构形变测量进行研究。本文开展了对空间引力波探测望远镜多自由度形变测量的研究,重点解决多自由度测量的耦合问题,并对误差来源进行详细分析。在空间引力波探测望远镜的研制阶段,该测量方法的研究有望满足望远镜多自由度形变测量的需求,为望远镜设计提供多自由度形变的数据反馈,为望远镜光程稳定性研究提供指导。
The space gravitational wave telescope is a key payload of gravitational wave detection satellites,responsible for both beam expansion and compression.Optical path stability is a crucial indicator for the telescope,closely related to its structural stability.To meet the stringent requirements for ultra-high optical path stability and structural stability in gravitational wave detection missions,it is necessary to investigate the measurement of structural deformations in the telescope.This paper presents a study on multi-degree of freedom deformation measurement for space gravitational wave telescopes,focusing on addressing the coupling issues in multi-degree of freedom measurement and conducting a detailed analysis of error sources.During the development phase of the space gravitational wave telescope,this measurement method is expected to meet the demands for multi-degree of freedom deformation measurement,providing data feedback on multi-degree of freedom deformations for telescope design and offering guidance for optical path stability research.
