摘要
快速反射镜是自适应光学中重要的光学元件,比较了有轴系和无轴系快速反射镜两种结构形式的性能,分析了不同的工作特点和应用特征,在此基础上设计了一种新的有轴系快速控制反射镜结构。轴系利用柔性轴承无摩擦、转角大的特点,通过分析计算提出了适用的参数,选择了相应的柔性轴承.该设计结合了有轴系和无轴系快速反射镜的优点,提出了一种具有发展前景的快速反射镜结构。
The fast steering mirror is an important optical component of adaptive optics, the structure proper- ties of shafting fast steering mirror and no-shafting fast steering mirror are compared, the difference working and application characteristics are analyzed, a new structure of fast steering mirror is designed on this basis. The flexible bearing has the characteristics of no friction and big angle, the shafting uses these characteristics. The applicable pa- rameters are proposed and the relative flexible bearing is selected by analyzing and calculating. The design com- bines the advantages of shafting fast steering mirror and no-shafting fast steering mirror, a structure of the fast steer- ing mirror which has a development prospect is proposed.
