Embodiments of the disclosure include a scanning mirror assembly for an optical sensing system. The scanning mirror assembly may include a scanning mirror formed in a first layer of the scanning mirror assembly. The scanning mirror assembly may also include a MEMS actuator formed in a second layer of the scanning mirror assembly, where the first layer is a predetermined distance above the second layer. The MEMS actuator may also include a plurality of stator actuator features and a plurality of rotatable actuator features formed from a same semiconductor layer during a fabrication process.
