Patent ID: 6975442

Claim:
A resonance scanner, comprising: an actuator, wherein the actuator further comprises a fixture, wherein a drive plate is operably coupled to the fixture by first torsion springs such that the drive plate operably oscillates about a common first axis of torsion of the first torsion springs and has a first eigenfrequency, wherein a mirror is operably coupled within and to the drive plate by second torsion springs such that the mirror operably oscillates about a common second axis of torsion of the second torsion springs and has a second eigenfrequency that is different from the first eigenfrequency, wherein the first axis of torsion and the second axis of torsion are substantially parallel; and a stator, wherein the stator comprises a driver operably arranged in an area defined by the drive plate, wherein the driver is operably controllable to allow direct application of force to the drive plate, wherein the applied force has a period tuned to the second eigenfrequency, wherein the stator further comprises a plurality of side walls and a bottom, and wherein the fixture comprises a frame operably coupled to the plurality of side walls, wherein the driver is operably coupled to the bottom of the stator, and wherein the bottom further comprises a recess operable to reduce damping of the mirror, the recess disposed to operably allow a maximum mechanical deflection of the mirror.
