In this paper , we brought forward an innovative idea : according to the characteristics of easy deformation of ultra - thin mirror , we employ a sphere mirror , which is easier to fabricate and test , to replace the aspherical mirror , then the sphere mirror is deformed into an aspherical one by active optics technology . on this purpose , we need to study the mechanism and method of shaping a spherical mirror into an aspherical one 由于非球面镜的加工和检测都比较困难,因此本文提出了一个大胆的设想:利用超薄镜易于变形的特点,以加工和检测难度远低于非球面的球面来代替非球面,运用镜面的主动控制技术将球面反射镜变形成所需精度的非球面反射镜。
