This paper shows that the task of trajectory planning for a dual-mirror optical pointing system with mechanical vibrations greatly benefits from carefully designed dynamic input signals, especially when high bandwidth throughput is required. The optical pointing system consists of two fast steering mirrors (FSMs) for which dynamically coupled input signals are designed, while adhering to mechanical and input signal constraints. A linear programming problem is used to compute the dynamic input signal for each FSM, with one acting as an image motion compensation device. The result is a dynamically coupled set of planned input signals that improve the overall tracking of the dual-mirror optical pointing system.
本文表明，对于存在机械振动的双镜光学指向系统，轨迹规划任务能从精心设计的动态输入信号中极大受益，尤其是在需要高带宽吞吐量时。该光学指向系统由两个快速转向镜（FSM）组成，针对这两个镜子设计了动态耦合输入信号，同时遵循机械和输入信号约束。使用线性规划问题来计算每个FSM的动态输入信号，其中一个FSM用作图像运动补偿装置。结果是一组动态耦合的规划输入信号，可改善双镜光学指向系统的整体跟踪性能。
