Optical Design and Performance Analysis of a High-Resolution Stable Stellar Simulator

The stellar simulator is an indispensable tool in astrophysics research and a laboratory test device used for star sensor testing and calibration. However, existing simulation technologies still face challenges such as a small usable field of view and low precision of the stellar simulator. Based on the current research status of stellar simulators at home and abroad, this paper determines the core parameter performance of the stellar simulator and designs the optical system of the stellar simulator based on these parameters. The optical system is optimized and designed in a normal temperature environment through the optical design software CODE-V, and a high-precision and large-field-of-view stellar simulator is designed. Design a star simulator with rms10.31 ", MTF> 0.85 and a total weight of 300g.
