摘　　要：为了实现大口径平面镜的原位检测,本文基于差分传递函数结合瑞奇康芒检测架构,利用全息检测方法结合瑞奇康芒法,通过光瞳的遮拦编码实现大口径平面镜的面形检测。首先,对基于差分传递函数法的大口径平面镜检测基本原理进行了推导,并将现有的大口径波前与重建波前进行对比。最后,利用变形镜搭建了检测光路。本文方法所得到面形与输入面形相关性不低于70%。本文的研究成果对宇宙“首光”探测以及“一黑两暗三起源”等宇宙学基础命题的研究均有十分重要的意义。In order to realize the in-situ detection of large aperture plane mirrors,wavefront detection is achieved by a combination of the Ritchey-Common method and holographic detection through the differential transfer function,combined with the actual Ritchey-Common detection architecture,and through the occlusion code of the pupil.Firstly,the principle of large aperture plane mirror detection based on differential transfer function method is derived,and the existing large aperture wavefront is compared with the reconstructed wavefront.Finally,the detection light path is built by using deformable mirrors.The correlation between the surface shape obtained by this method and the input surface shape is not less than 70%.This paper is of great significance to the fundamental cosmological propositions such as the detection of the"first light"of the universe and the"one black,two dark and three origins".
