The physical model of polarizing beam coupling and splitting system using altazimuth coude telescope is built up based on Mueller matrix and Stokes vector. The phenomena of the decreasing of the receiving efficiency are successfully explained by this model. Three dynamic phase compensation solutions are proposed: 1 Two quarter-wave plates are rotated to compensate the phase of the laser.
针对这个问题,建立了地平式折轴望远镜的共孔径偏振耦合分光模型,用Stokes矢量和Mueller矩阵分析了在望远镜旋转过程中激光偏振态的变化,数值模拟计算了望远镜处于不同方位角和天顶角时的偏振耦合分光效率,解释了实验中观察到的望远镜旋转导致偏振耦合分光效率退化的现象。

Reflector telescope relative a larger diameter can be done, the main focus of the relative telescope diameter is about 15-125, even greater, Wang DC, inter Newton Telescope, the tube is longer than the system is much shorter focal length, coupled with the main mirror is only one apparent need for processing, which greatly reduces cost and manufacturing difficulties, there is currently greater than 134 meters diameter optical telescopes are all reflecting telescope.
反射望远镜的相对口径可以做得较大,主焦点式反射望远镜的相对口径约为15—125,甚至更大,而且除牛顿望DC远镜外,镜筒的长度比系统的焦距要短得多,加上主镜只有一个表面需要加工,这就大大降低了造价和制造的困难,因此目前口径大于134米的光学望远镜全部是反射望远镜。

Accordingly, as the major targets weighing the quality of the telescope,its luminous energy concentration degree directly influence the quality of the image of the celestial body. So many kinds of technique about the optical quality testing of telescope have came forth. Hartmann screen test is one of the most classical among them and it has become one of the main testing method on several large-scale telescopes in the world because of some strongpoints suchas briefness, visuality and easy handlment.The image through the350mm telescope of the Yunnan observatory has aberration in general, subsequently,the relative position of the primary mirrior has err when blooming and reinstalling .
因此,天文望远镜光能集中度作为衡量天文望远镜质量的重要指标,直接影响到所成天体像的质量好坏,所以就出现了多种天文望远镜光学质量检测方法,其中最经典的是哈特曼光栏法,它因简单、直观、操作方便等优点而成为世界上多台大型天文望远镜的重要质量检测方法之一。
