DISC RESONATOR INTEGRAL INERTIAL MEASUREMENT UNIT |
摘要 |
Sensing motion of multiple degrees of freedom for an integral inertial measurement unit provided through the operation of a single centrally mounted planar disc resonator having a single driven mode in a single vacuum enclosure is disclosed. The resonator comprises a circumferentially slotted disc having multiple internal capacitive electrode s within the slots in order to excite a single in-plane driven vibration and sense in-plane vibration modes or motion of the resonator. In addition, vertical electrodes disposed below and/or above the resonator may also be used to sense out-of-plane vibration or motion. Acceleration sensing in three orthogonal axes can be obtained by sensing two lateral modes of the disc resonator in t he plane of the disc from the internal electrodes and a vertical mode from the vertical electrode s.
