摘要
为了获得更高质量的观测数据，提高望远镜的工作效率，设计了一套基于倾斜镜校正系统的原理样机，用于提高丽江2.4 m望远镜的闭环跟踪精度。介绍了原理样机的研制，并在2.4 m望远镜上进行了实际测试。结果表明：该系统能实现245 Hz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。
Abstract
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 tracking precision of the 2.4-meter telescope in Lijiang. This paper introduces the development of the prototype and carried out the actual test in the 2.4-meter telescope. The results show that the system can realize the correction frequency of 245 Hz, and the closed-loop tracking precision of the telescope is improved by 7.3 times. Meanwhile, the coupling efficiency of the high resolution echelle spectrograph is improved by 28.6%, the imaging quality of the fast photometry system is improved obviously. The system can meet the requirements of astronomical observation.
