Fast Steering Mirrors
Piezo Stages
A Fast-Steering Mirror (FSM) solution includes a Mirror integrated on a steering platform (Tilt or Tip/Tilt), positions sensors and a controller. CTEC COTS FSM and steering platforms are either piezo or magnetic actuator-based mechanisms. They are controlled with either piezo controllers or magnetic controllers. Their sensors are either Strain Gauges (SG) or Eddy Current Sensors (ECS).
As an option for COTS Tilt or Tip/Tilt platforms, CTEC can propose to outsource and to integrate a suitable mirror defined in collaboration with the customer. CTEC can even design customized mirrors (Silicon Carbide SiC, Fused Silica SiO2, …).
COTS FSM and COTS Tilt or Tip/Tilt Platforms are presented below. A dedicated brochure Fine and Fast Steering Mirrors as well several publications presents the customized and OEM FSM solutions already delivered by CTEC to the Space, Optronics and industrial Electro Optic markets.
