摘要	Aiming at the problem of image stabilization precision testing of large-aperture space telescopes being developed in China, this paper proposes a high spatiotemporal resolution motion guide star simulation scheme. Firstly, the silicon-based liquid crystal is used as the motion guide star simulation source, and the beam alignment system is combined to provide the infinite motion guide star for the space telescope. The objective lens is added to the light path to improve the motion resolution of the simulated guide star. Then, owing to the special distribution of the telescopic mirror surface structure, a method for simulating the multichannel optical path is proposed to provide real-time moving guide stars for the precision guide sensor on both sides of the telescope and the survey image surface. Finally, the error sources that affect the simulation accuracy of the moving guide star are analyzed, and the error model is established. The simulation results show that under the assumption that the simulation accuracy of the moving guide star is better than 0.5", with probability of 95% and time-resolution of 3 ms, the precision simulation of the interstar angular distance error of the dynamic star map is less than 0.04" and the angle is the single star of less than 0.02". The simulation model was verified by experiments and meets the requirements of high spatiotemporal resolution of moving guide star targets for image stabilization accuracy testing of space telescopes. 2020, Science Press.
