Abstract
A mirror device includes a mirror, an actuator tilting the mirror, a first hinge coupling the mirror to the actuator, a base, a second hinge coupling the mirror to the base, a movable comb electrode coupled to the mirror, and a fixed comb electrode fixed to the base. The actuator is controlled based on a capacitance between the movable comb electrode and the fixed comb electrode. The movable comb electrode is disposed on a portion of the mirror closer to the second hinge than to the first hinge.
