【摘要】：下一代大口徑望遠(yuǎn)鏡有兩個特點,一是主鏡通過拼接而成,且是通過主動光學(xué)來控制它們之間的平移、傾斜誤差;二是采用自適應(yīng)光學(xué)來校正大氣湍流。因此分析拼接誤差對拼接鏡像質(zhì)的影響,對下一代望遠(yuǎn)鏡發(fā)展有重要意義。通過理論及數(shù)值仿真分析了拼接式主鏡中平移、傾斜誤差以及邊緣誤差對拼接鏡成像質(zhì)量的影響,通過理論與仿真分析可知拼接鏡平移誤差與傾斜誤差對拼接鏡成像質(zhì)量的影響是相互獨立的,邊緣誤差對拼接鏡像質(zhì)的影響較小。
[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.
