Abstract
Embodiments of the disclosure provide a mirror assembly for controlling optical directions in an optical sensing system. The mirror assembly may include a frame and a beam structure mechanically coupled to the frame. The beam structure may define a rotational axis. The mirror assembly may also include a micro mirror suspended by the beam structure. The mirror assembly may further include a plurality of piezoelectric actuators mechanically coupled to the frame and configured to rotate the micro mirror along the rotational axis. Each of the plurality of piezoelectric actuators may be disposed between the rotational axis and an outer edge of the frame.
