查询词典 vector subspace

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。
