Fine Steering Mirrors Provide High Speed and Precision Control for Free Space Optical Laser Communications |
|
(Nanowerk News) PI is extending its offering of fast steering mirrors. The new V-931 two-axis fast steering mirror platform (FSM) is based on a frictionless, precision flexure guiding mechanism, with differential voice-coil drives and optical feedback for accurate closed-loop angular position control. | |
The compact, durable design produces a beam deflection angle to 8° in theta-X and theta-Y, with symmetrical motion characteristics delivered by its parallel kinematics design. The angular resolution of the standard model is 1 µrad (higher resolution models are available). The two orthogonal tip/tilt axes share a common center of rotation, providing significantly better performance, free of polarization rotation issues, while reducing package size, compared to older designs based on stacking two individual scanning axes. | |

Laser and Imaging Applications in Industry and Space Applications |
|
PI has a long track record of designing fast precision mechanisms for laser scanning, optical communications, and image stabilization for industrial, astronomy, and aerospace projects. A PI piezo steering mirror is currently on board the NASA/ESA Solar Orbiter Satellite, orbiting the sun. PI precision motion equipment is also embedded in the Curiosity Mars rover and the new Perseverance rover. | |
