Paper Abstract

This paper contains a discussion of the functions of fast steering mirrors (FSMs) in optical systems which include target tracking, attenuation of disturbances including jitter, alignment beam and image stabilization, and extending optical sensor linear range. Dynamic and control modeling of the FSM mechanism, actuators, position sensors, and controllers are described in terms of mass and inertia properties, dynamic range, and bandwidth. Illustrative examples of the use of FSMs in optical systems and a simulation of a representative optical system using an FSM and corresponding results are shown. The use of software tools in performing control systems simulations is discussed.
