Free-Space Optics (FSO) for optical communication request new compact low-power high-stroke high-bandwidth Fast Steering Mirrors (FSM). To address this need, CEDRAT TECHNOLOGIES has developed a Magnetically-actuated Fast Steering Mirror called M-FSM, taking heritage of its MICA(TM) actuators. This FSM offers Rx Ry strokes larger than +/- 2deg with a 250 Hz bandwidth when tilting a diameter 31 mm mirror. Requested power is minimized leading to low heating. Vibration tests have been performed to define first limits and conditions for the M-FSM to bear external vibrations. Large bandwidth closed loop control is achieved using integrated eddy current sensor and a state feedback-based controller.
