Research Progress in Jitter Measurement and Suppression Technology for Large-Aperture Optical Telescopes

大口径光学望远镜在未来深空探测技术中具有重要发展意义,其性能提升将对光轴抖动的测量和抑制提出更高要求。本文对国内外有关抖动测量与抑制技术的研究文献进行了整理,涵盖了接触式和非接触式的测量方法,振源设备、传递途径和光学载荷的抑制技术,以及系统集成分析技术。总结了抖动测量与抑制的研究现状,指出目前研究多集中在局部实验或模拟,缺乏整体系统的解决方案,并提出集成分析方法结合测量与抑制技术将成为未来的研究热点。

Large-aperture optical telescopes are important for the development of the future deep-space detection technology,and their performance improvement will lead to higher requirements for the measurement and suppression of optical axis jitter.In this context,this article summarizes literature on jitter measurement and suppression techniques,published domestically and internationally,covering contact and noncontact measurement methods,suppression techniques for vibration source equipment,transmission pathways,and optical loads,and system integration analysis techniques.The analysis of the current research status regarding jitter measurement and suppression reveals that current research primarily focuses on local experiments or simulations,lacking a comprehensive system solution;hence,it is proposed that integrated analysis methods combined with measurement and suppression technology will become a future research hotspot.
