Abstract
A light steering system includes: a reflective structure configured to tilt about a first axis; a frame that includes a frame recess over which the reflective structure is suspended; and a suspension assembly that includes a piezoelectric corrugated structure coupled to and between the reflective structure and the frame. The piezoelectric corrugated structure includes a first corrugated surface including concentric rings of alternating peaks and valleys; a second corrugated surface arranged opposite to the first corrugated surface; a plurality of peak electrodes, each peak electrode being coupled to a respective peak of the first corrugated surface; a plurality of valley electrodes, each valley electrode being coupled to a respective valley of the first corrugated surface; and a common electrode layer coupled to the second corrugated surface, wherein the common electrode layer is arranged counter to the plurality of peak electrodes and to the plurality of valley electrodes.
