Original Abstract Submitted

A MEMS mirror is provided with two rotation axes. The MEMS mirror includes a frame with a reflector and piezoelectric actuators inside, and support beams, with moving comb fingers, which alternate with static comb fingers and form electrostatic actuators. A double device layer allows separating the static comb fingers from the rest of the parts of the MEMS mirror by placing them at a different device layer. The configuration maximizes the tilt displacement and broadens operating range of the MEMS mirror. Additionally, using electrostatic comb actuator for slow drive allows effective operation in quasi-static and static modes.
