Abstract
Polarization basis vector’s maintenance and detection are important factors in satellite-ground quantum optical communication. In this paper, a double frequency orthogonal beacon light system is designed to transfer three-dimensional attitude and the beacon light is sent to the attitude decoupling system for angle decoupling in the ground. Synchronous online measurement of pitch angle, azimuth and polarization basis vector angle of beacon light is realized. Transfer process of polarization light on the coating interface is analyzed and the influence of the optical components on the phase, reflection rate and transmission rate is simulated. Three-dimensional attitude of beacon light detection by two dimensional PSD is researched and experiments are realized to confirm its feasibility.
