The Design of MEMS Scanner for the Three Dimensional Actuation with a Pair of Beams

Abstract

We propose the design for three-dimensional (3-D) scanning micromirror with single pair of beams. A 3-D scanning micromirror is powerful solution for projection/detection of a 3-D image in tiny devices. We succeed in designing and fabricating the micromirror having three separated resonance modes (two torsion modes and one parallel mode) with high fill-factor. Our design of single pair of beams can contribute to simpleness and compactness of a 3-D scanner because of easy fabrication and high fill-factor.
