| Abstract: | A purpose for dynamic MEMS characterization is to provide relible experimental data feedback to the process of design and fabrication of movable MEMS devices. A dynamic measuring system was built up using some optical methods, which are non-contact, fast, and high precision. This system employed optical flow technology and microscopic interferometry combining with stroboscopic illumination to realize the measurement of in-plane and out-of-plane motions of MEMS devices. The capabilities of the system are illustrated with a study of the dynamic behavior of a micro-machined lateral resonator. |
