Abstract: A positioning system, including: a first plate; a second plate coupled to the first plate and pivotable about an axis; a pair of voice coil actuators configured to rotate the second plate about this axis; and a processor configured to drive currents to the pair of voice coil actuators; wherein the pair of voice coil actuators comprises a first and second magnet structures mounted on the first plate at equal and opposite distance from the axis, and a first and second coils mounted on the second plate and positioned such that the respective first and second magnet structures move in and out of the first and second coils when the second plate rotates about the axis; wherein each of the first and second magnet structures substantially conforms to an arc having a center at the axis and a radius equal to the distance of the magnet structure from the axis.

Abstract: A fast steering optical mirror for laser beam deflection, moved by at least one rotational axis, including: a plate containing a plurality of carbon fiber layers laid up in a resin, wherein the plate includes a front face, at least a portion of the front face being polished and coated for laser light reflection; and wherein a surface normal of the front face is aligned orthogonal to the at least one rotational axis. A method of manufacturing fast steering optical mirror including: forming a plate having a front face and a back face by laying up a plurality of carbon fiber layers in a resin; aligning the plate so that a surface normal of the plate is orthogonal to at least one rotational axis of the mirror; and polishing and coating at least a portion of the front face for light reflection.
