查询词典 telescope

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.
