Abstract

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.
