Abstract
A system and method for providing a resonant beam sweep about a first axis. A mirror or reflective surface supported by a first pair of torsional hinges is driven into resonant oscillations about the first axis by inertially coupling energy through the first pair of torsional hinges. A light source reflects a beam of light from the mirror such that the oscillating mirror produces a beam sweep across a target area. The resonant beam sweep is moved orthogonally on the target area by a gimbals portion of the mirror pivoting about a second axis according to one embodiment. A second independent mirror provides the orthogonal movement according to a second embodiment.
