从成功的Keck望远镜设计出发，构造并分析了一种通用分段式望远镜主镜主动控制系统的控制矩阵，该控制矩阵包含了Keck望远镜的另一种传感器几何结构，可达1000个分段。特别是，我们研究了矩阵的噪声传播及其对视界和绕射受限观测的影响。根据支配后一个问题的不同但相关的矩阵，还分析了这种主镜的光学对准的相关问题。(C)2004年美国光学学会。
Starting from the successful Keck telescope design, we construct and analyze the control matrix for the active control system of the primary mirror of a generalized segmented-mirror telescope, with up to 1000 segments and including an alternative sensor geometry to the one used at Keck. In particular we examine the noise propagation of the matrix and its consequences for both seeing-limited and diffraction-limited observations. The associated problem of optical alignment of such a primary mirror is also analyzed in terms of the distinct but related matrices that govern this latter problem.
