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.
