摘要
Abstract
Some new kinds of torsion micromirrors with advanced compound driving structures as well as novel folding torsion-spring structures are proposed and fabricated in SOI wafers by combing with bulk micro machining and surface micro machining technology to improve the electromechanical performances and the optical properties of torsion micromirrors. To evaluate the mechanical robustness and the electrical response, the electromechanical performances of the components are investigated experimentally and theoretically. At the same time the surface roughness of the micromirrors is measured and analyzed to characterize the optical properties of the micromirrors. And then some parameters which greatly affect the mirror's total performance are obtained.The theoretical and experimental studies manifest that the compound driving structures and folding torsion-spring structures are much benefit to decreasing the yielding voltages of actuating the micromirrors and, thus, making their tilting motion easier.关键词
