Abstract:
A rolling micromirror for reflecting an incident light beam, the rolling micromirror comprising:a micromirror; an actuator, the actuator operatively coupled with the micromirror and for moving the micromirror; a suspension element, the suspension element operatively coupled with the micromirror, and the suspension element providing a restoring force to the micromirror when the micromirror is out of an initial position, wherein the restoring force returns the micromirror to the initial position; and a reference surface, the reference surface for guiding the motion of the micromirror in more than one dimension, wherein the micromirror maintains contact with the reference surface, and the contact between the micromirror and the reference surface moves when the micromirror moves, whereby the micromirror redirects the light beam.
