Patent ID: 7453618

Claim:
A device comprising a scanner having a mechanical center of rotation axis, an optical center of rotation, and a pitch axis orthogonal to the mechanical center of rotation axis, the scanner comprising: a reflective prism for circularizing an elliptical input scanning beam to provide a circularized output scanning beam; a prism carrier and magnet suspension assembly from which the reflective prism is mounted; flexure means connected to the carrier and suspension assembly for enabling the reflective prism to controllably pivot: at one end of the reflective prism with respect to the mechanical center of rotation axis so to that the output scanning beam provides a scan which is stationary with respect to the optical center of rotation; and with respect to the pitch axis so that the output scanning beam provides an orthogonal scan; a magnet component which, when actuated, causes the reflective prism to controllably pivot with respect to one or more of the mechanical center of rotation axis and the pitch axis; and means for actuating the magnet component to thereby cause the reflective prism to controllably pivot with respect to one or more of the mechanical center of rotation axis and the pitch axis.
