摘要

摘要: 随着以双曲面为次镜的两镜光学系统在天文和空间光学等领域的应用日趋广泛,双曲面次镜的口径和相对口径越来越大,由此对双曲面次镜的面形检测技术提出了很高的要求。本文基于国外有代表性的双曲面次镜参数分析了其基本特征和发展趋势,重点介绍了国外大型双曲面次镜的面形检测技术,并对其中的关键技术进行了分析。同时,概述了国内双曲面次镜检测技术现状。最后,总结和展望了大型双曲面次镜面形检测技术发展趋势。提出今后一段时间内,高均匀性的光学透射材料,高精度、大口径的辅助元件以及基于子孔径拼接的检测方法和数据处理方法是该领域的研究重点。

Abstract: With the large applications of the two-mirror optical system with hyperboloidal secondary mirror to astronomical and spacial fields, the aperture and relative aperture of the mirror grow larger and larger, which demands the measurement techniques to be improved greatly. According to the parameters of internationally typical hyperboloidal secondary mirrors, the basic specification and developing trends of secondary mirror is analyzed. The surface measurement method in overseas for the secondary mirror is emphatically introduced, and the corresponding key techniques and applicability are analyzed. In addition, the status of surface measurement method in our country for the mirror is also introduced. Finally, the developing trends of surface measurement technology for the secondary mirror are summarized and prospected, it points out that the research on measurement method in future should focus on the transmission materials with high homogeneity, high precision and large aperture auxiliary components and the measurement methods and data processing based on sub-apeature stitching.
