摘要
提出了一种基于二维振镜与位置灵敏探测器的高精度激光跟踪系统;基于光线追迹方法建立跟踪系统的几何光学模型,并对跟踪系统进行误差分析,通过仿真对激光跟踪系统的指向精度以及跟踪性能进行分析。仿真结果表明:在跟踪距离100 m处,跟踪系统的位置指向精度可达0.35 mm,角度指向精度为0.72″,跟踪范围为-10°~10°,最大跟踪速度可达3.6 rad/s,能够实现对远距离快速运动目标的高精度实时主动跟踪。
A high-precision laser tracking system based on a two-dimensional galvanometer and position sensitive detector is proposed. A geometrical optics model of the tracking system is established using the ray tracing method, and error analysis is performed to simulate positioning precision and tracking performance of the proposed laser tracking system. Simulation results demonstrate that, when the target is located at a distance of 100 m, the tracking system's point position precision is 0. 35 mm, angular precision is 0. 72", tracking range is - 10° to 10°, and maximum tracking speed is 3.6 rad/s. These results indicate that the system can realize high precision and real-time active detection tracking for fast moving targets at long distances.
