Fast Steering Mirror (FSM)
“Precision Tip-Tilt Platforms with Mirror Payload”
A Fast Steering Mirror (Tip-Tilt Platform with Mirror Mounted) performs rapid tip-tilt (2 Axis) to allow precision light/laser/energy pointing.
A set of fast response (order of kHz) and precise (order of nm) piezo actuators are used to tip/tilt and are maintained in precise closed loop position control by balanced strain sensor bridge.
Compliant flexure mechanisms and Zero free-play pivot allow the range and bandwidth of operation
Major applications of the same are
Laser beam stabilization
Defence & directed energy systems
Free-space optical communication
Aerospace & airborne optics
Adaptive optics
Precision tracking systems
Industrial laser systems
Medical laser equipment
