    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.
