| 摘要 |
<p>The invention relates to a micromechanical gyroscope comprising a substrate, at least one gyroscopic element comprising a mass element, suspension means for flexibly connecting the mass element with respect to the substrate, means for exciting the mass element into a vibrational mode and sensing means for detecting vibrational characteristics of the mass element. According to the invention, the vibrational mode is a bi-directional orbiting mode and the sensing means are adapted to detect changes in vibrational characteristics of the orbiting mode, such as a phase shift or change in resonance frequency or orbiting radius of the orbiting mode caused by external rotational motion. The invention helps to improve the signal-to-noise ratio of micromechanical gyroscopes.</p> |
