PI offers a selection of high-speed steering mirrors for laser beam control and stabilization for free space optical communication. Both voice-coil driven units and piezoelectric type mirror platforms are available. The new V-931 two-axis fast steering mirror platform 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.
