Through mathematical analysis, the constraints related to mirror surface deformation are boiled down to the components of sine and cosine varying with elevation. With the use of Gregorian telescope, a real-time phase compensation system matching with the constraints is induced. 经数学分析,将与镜面变形相关的约束归结为根据仰角变化的正弦分量和余弦分量,相应地使用戈里高利型望远镜,引入与约束相匹配的实时相位补偿校正系统。
