Abstract
Embodiments of the disclosure provide a scanner for steering optical beams. In certain configurations, the scanner may include a micro-electromechanical system (MEMS) scanning mirror independently rotatable around a first axis and a second axis orthogonal to the first axis. The scanner may further include a piezoelectric actuator coupled to the MEMS scanning mirror, where the piezoelectric actuator has a first pair of piezoelectric electrodes configured to drive the MEMS scanning mirror to rotate around the first axis, and a second pair of piezoelectric electrodes configured to drive the MEMS scanning mirror to simultaneously rotate around the second axis.
