摘要
消像旋机构是地基大型光学望远镜保证成像清晰的关键执行机构,在运用中必须满足高精度、结构紧凑、形变小等要求。随着对望远镜的性能和功能要求不断提高,望远镜的光学系统也更加丰富,消旋机构的结构设计也迎来新的挑战。为了寻找消旋机构的可行方案,给消旋机构的研究人员提供系统的参考,文本聚焦于地平式望远镜的发展需求,介绍了像旋特点和不同光学系统对应的消旋机构,进行整理、汇总、分类和对比,最后综合各消旋机构的特点,对消旋机构未来的发展趋势做出展望。
The image de-rotation mechanism serves as a critical actuation component in ground-based large optical telescopes,essential for ensuring imaging clarity through stringent requirements including high precision,compact structure,and minimal deformation.With the continuous advancement in the performance and functionality requirements of telescopes,optical systems have become increasingly sophisticated,thereby presenting new challenges for the structural design of de-rotation mechanisms.To explore viable solutions for these mechanisms and provide systematic references for researchers,this study addresses the developmental demands of alt-azimuth-mounted telescopes.It systematically examines the characteristics of im‑age rotation and corresponding de-rotation mechanisms across diverse optical systems,followed by comprehensive organization,summarization,classification,and comparative analysis.A forward-looking perspective on future trends in de-rotation mechanism development is presented in the conclusion of the paper,building upon the distinctive features of various derotation mechanisms.A theoretical foundation and technical framework for advancing next-generation high-performance derotation systems are established by this work.
