Abstract
Embodiments of the disclosure provide a scanning mirror assembly. In certain configurations, the scanning mirror assembly may include a two-dimensional micro-electromechanical system (MEMS) scanning mirror, a first pair of piezoelectric electrodes coupled to the MEMS scanning mirror through a first pair of looped torsion springs, and a second pair of piezoelectric electrodes coupled to the MEMS scanning mirror through a second pair of looped torsion springs. The first pair of piezoelectric electrodes drives the MEMS scanning mirror to rotate around a first axis. The second pair of piezoelectric electrodes drives the MEMS scanning mirror to rotate around a second axis orthogonal to the first axis.
