Paper Abstract
In a ring-type resonator as a solid-wave gyroscope, geometric distortions due to microfabrication tolerances perturb the dynamics of the vibration modes used for angular rate sensing, thereby limiting the sensing accuracy. The imperfection of the ring shape causes an unwanted frequency split between the modes. The post-fabrication modal frequency tuning requires the information about the node/antinodes orientation of the standing waves. In this work, we investigate the vibration behavior of micromachined ring-type resonator using a laser vibrometer. Frequency response is measured around the eigenfrequencies of the second order in-plane modes. The node/antinodes location is detected from the frequency response received at the different points of the ring.
