激光通信四象限探测器捕获与跟踪复用 optical communication four-quadrant detector acquisition and tracking multiplexing

摘要

针对空间激光通信系统小型化设计的需求，提出了使用四象限探测器实现捕获与跟踪的方案。通过分析四象限探测器上光斑的位置分布，推导了三种光斑分布的4QD 捕获牵引模型，通过对4QD 光斑位置的解算以及与跟踪机构的精准标定，实现了4QD 的高精度跟踪。在实验室基于一台激光终端与系统测试平台，对四象限探测器的捕获与跟踪方案及性能进行了实验验证，测试结果表明，在实验室动态条件下，用4QD 作为捕获及跟踪探测器，捕获概率高达100%，跟踪精度优于3 μrad，验证了该方案的可行性，为激光终端小型化设计奠定了基础。

Abstract

Aiming at the space laser communication system requirement of miniaturization, this paper proposes a scheme of using the four-quadrant detector to complete the acquisition and tracking. By analyzing the position distribution of the spots on the four-quadrant detector (4QD), the acquisition models are derived for the three kinds of spots distribution. Through the calculation of the position of the spots and the accurate calibration of the tracking mechanism, the high precision tracking is realized. Then besed on the laserteco and system test platform the capture and tracking scheme and detection performance of the 4QD are experimentally verified. The test results show that under the laboratory dynamic conditions, using 4QD as the capture and tracking detector, the capture probability is up to 100%, and tracking accuracy is better than 3 μrad, which verifies the feasibility of the scheme and lays a foundation for the miniaturization design of the laser terminal.
