Abstract
Embodiments of the disclosure provide a mirror assembly for controlling optical directions in an optical sensing system. The mirror assembly may include a substrate and a micro mirror suspended over the substrate by at least one beam. The at least one beam may be mechanically coupled to the substrate. The mirror assembly may also include an actuator configured to tilt the micro mirror with respect to the substrate. The mirror assembly may further include a position sensor configured to detect a position of the micro mirror. Moreover, the mirror assembly may include a bias voltage source electrically coupled to the substrate to bias the substrate with a bias voltage.
