【摘要】：下一代大口径望远镜有两个特点,一是主镜通过拼接而成,且是通过主动光学来控制它们之间的平移、倾斜误差;二是采用自适应光学来校正大气湍流。因此分析拼接误差对拼接镜像质的影响,对下一代望远镜发展有重要意义。通过理论及数值仿真分析了拼接式主镜中平移、倾斜误差以及边缘误差对拼接镜成像质量的影响,通过理论与仿真分析可知拼接镜平移误差与倾斜误差对拼接镜成像质量的影响是相互独立的,边缘误差对拼接镜像质的影响较小。
[Abstract]:The next generation of large aperture telescopes have two characteristics, one is that the primary mirror is made by splicing, and the other is that the translation and tilt error between them are controlled by active optics, and the other is to use adaptive optics to correct atmospheric turbulence. Therefore, it is important for the next generation telescope to analyze the effect of splicing error on splicing mirror quality. The effects of translation, tilt error and edge error on the imaging quality of the spliced primary mirror are analyzed by theoretical and numerical simulation. Through theoretical and simulation analysis, it can be seen that the effects of translation error and tilt error on the image quality of splicing mirror are independent, while the influence of edge error on the image quality of splicing mirror is small.
