摘　　要：通过设计正交偏振光信标器,实现了空间信标姿态的单光路传递,为星地量子光链路的建立提供了条件.通过分析光学器件,尤其是镀膜器件中偏振信标光的传递特性,仿真分析不同入射角、旋转角条件下,出射信标光的偏振模式.分析了由光学器件引入的位相差和不同反射率、透射率对偏振模式的影响.利用琼斯矩阵推导了马吕斯定律在椭圆偏振光入射时的表达形式,建立起测量椭圆偏振光主偏振方位角模型.利用光电位置传感器接收正交信标光,结合光电位置传感器的光点位置检测能力解耦信标光的俯仰角和方位角,利用光电位置传感器的光强探测能力解耦信标光的偏振基矢角,实现了单器件三维信标姿态测量.实验表明,所述系统具有完成信标光三维姿态检测的能力,可用于星地量子光通信、空间信标姿态检测.By using the design of the orthogonal polarized light beacon,the single optical path transmission of space beacons gesture was achieved,which provied the conditions for the Satelite-Ground quantum optical link.The transmission characteristic of the polarization through the optical device,especially the coated device was analyzed.A simulation was done to analyze the outgoing beacon light under the condition of the different incident angles and rotation angles.The influence by the phase and reflectivity difference in the optical components was analyzed.A mathematical model of the measurement of polarization azimuth by using the Jones matrix was made to analyze the form of the Malus law in the elliptic polarized light incident.Three-dimension attitude can be obtained by a single Position Sensitive Detector sensor which can receive the beacon light,decouple the angle of polarization and the location of incident light.The experiment data shows that the system has the function of measuring three-dimension attitude of the beacon by a single Position Sensitive Detector sensor.This system provides a solution to the fields of the Satelite-Ground Optical Communication and the measurement of space geometry position.
