摘要
为提高大型光电望远镜的成像质量,需要实时调整次镜与主镜之间的相对关系来保证光路的吻合。提出了一种基于Stewart平台的次镜支撑与调整方案以满足系统需求。1)从理论上对Stewart平台的结构和原理进行了详细的分析;2)通过试验对Stewart平台的精度、重复性和线性度进行了测试。结果表明,Stewart平台是作为次镜调整机构的一种理想选择。
In order to improve the image quality of large optical telescope,the relative relationship between the secondary mirror and the primary mirror should be adjusted to ensure consistent of light path.In this paper a secondary mirror sup- port and adjustment program based on Stewart platform is presented to meet system requirements.Firstly,Stewart plat-form structure and principle are analyzed.Secondly,the accuracy,repeatability and linearity of Stewart platform are tested through experiments.The results show that Stewart platform is an ideal choice for secondary mirror adjustment.
