PI (Physik Instrumente) offers a big selection of high-precision quick steering mirrors. Two varieties can be found: piezoelectric tip/tilt mirrors and voice-coil-driven models. Whereas piezo-driven mirror mounts present extraordinarily excessive decision and responsiveness, voice-coil drives obtain bigger angles.
The brand new V-931 two-axis quick steering mirror platform (FSM) is predicated on a frictionless, precision flexure guiding mechanism, with differential voice-coil drives and optical suggestions for correct closed-loop angular place management. The compact, sturdy design produces a beam deflection angle to eight° in theta-X and theta-Y, with symmetrical movement traits delivered by its parallel kinematics design. The angular decision of the usual mannequin is 1µrad (greater decision fashions can be found). The 2 orthogonal tip/tilt axes share a typical middle of rotation, offering considerably higher efficiency, freed from polarization rotation points, whereas decreasing bundle measurement, in comparison with older designs primarily based on stacking two particular person scanning axes.
Laser and Imaging Functions in Trade and House Functions
PI has an extended observe report of designing quick precision mechanisms for laser scanning, optical communications, and picture stabilization for industrial, astronomy, and aerospace tasks. A PI piezo steering mirror is at the moment on board the NASA/ESA Photo voltaic Orbiter Satellite tv for pc orbiting the solar. PI precision movement tools can also be embedded within the Curiosity Mars rover and the brand new Perseverance rover.
