Abstract:
1. A micromirror device comprising: (a) a substrate having left and right sides; (b) at least two protruded support posts arranged protrudedly on the left and right sides from a surface of the substrate, the protruded support posts separated by a predetermined interval from each other; (c) multiple cantilevers formed substantially parallel to the surface of the substrate, each having two ends, one end being attached at an upper end portion of respective protruded support posts and made in a thin strip having an elastic restoring force, wherein adjacent cantilevers are arranged to be substantially parallel and the cantilevers are interdigitated; (d) mirror support posts coupled to upper portions of other ends of the cantilevers; (e) a mirror attached on upper portions of the mirror support posts and supported by the mirror support posts; and (f) two electrodes formed at the left and right sides on the substrate, for providing an electrostatic force to the mirror, wherein the mirror, without pivoting, reflects incident light in different directions based on the electrostatic force due to a voltage applied between the electrodes and the mirror, and based on the elastic restoring force of the cantilevers.
