FEATURES

The custom design of or built-to-print Fast Steering Mirror (FSM) incorporates a mirror mounted to a flexure support system that is tilted to direct a laser beam or other light source. A set of voice coil actuators or eddy current sensors are used to provide the directional motion for complete precision and low jitter functionality.

The system offers either open-loop and closed-loop operation. For closed-loop operation, integrated high-speed precision sensors are used to provide a complete feedback control system. With its modular design, the FSM allows increased flexibility in mirror substrate choice, aperture size, degrees of tilt and control electronics to meet any mission requirements.
