Abstract：In order to complete the calibration work of the star sensor and meet the technology requirement of large field, high accuracy for dynamic star simulator, the ZEMAX software is used to complete the design of the optical system according to the dynamic star simulator working principle, which can accurately simulate the star point. The experimental results show that the focal length of the system is 110 mm, the field of view is 16°, the distortion is less than 0.05%, the wave range is 0.5～0.8 μm and the MTF is higher than 0.7 at the frequency of 60 lp/mm. The method to determine the actual focal plane of the system after assembly is put forward, and then the precision of the optical system are analyzed. The results show that the imaging accuracy design of high-precision dynamic star simulator optical system can reach 9″, and the error between stars is less than 13″. So the whole system can meet the using need of the high-precision dynamic star simulator.
