Abstract:

拼接镜作为更大口径天文望远镜的发展趋势之一，其各子镜之间存在的共相误差对拼接镜的成像质量有着非常大的影响。本文理论分析了共相误差之一——平移误差对拼接镜成像质量的影响，并对不同波长下平移误差对拼接镜系统点扩散函数的影响进行了仿真分析。
As one of the development trends of larger aperture astronomical telescopes, the common phase errors among the sub-mirrors of the mosaic mirror have a great impact on the image quality of the mosaic mirror. In this paper, the effect of piston error, one of common phase errors, on image quality of stitching mirror is analyzed theoretically, and the effect of translation error on point spread function of stitching mirror system under different wavelengths is simulated and analyzed.
