为了获得更高质量的观测数据并提高望远镜的工作效率,设计了一套倾斜镜校正系统的原理样机,用于提高丽江2.4米望远镜闭环跟踪精度的研究。本文介绍了倾斜镜技术原理样机的研制,并在2.4米望远镜上进行了实际测试。结果表明,该系统能实现245Hz的校正频率,望远镜的闭环跟踪精度提高了7.3倍,其高色散光谱仪的星光耦合效率因此提高了28.6%,快速测光系统的成像质量得到了明显改善,利用该系统可以满足对天文观测的要求。 

A prototype based on the tip-tilt mirror correction system is designed to obtain higher quality observation data and improve the efficiency of the telescope, which is used for the research on improving closed-loop trackingprecision of the 2.4-meter telescope in Lijiang. This paper introduced the development of the prototype and carried out the actual test in the 2.4-meter telescope. The results showed that the system can realize the correction frequency of 245Hz, and the closed-loop tracking precision of the telescope was improved by 7.3 times. Meanwhile, the coupling efficiency of the High Resolution Echelle Spectrograph was improved by 28.6%, The imaging quality of the fast photometry system had been improved obviously, the system can meet the requirements of astronomical observation.
