Vibrating gyroscope

摘要

The gyroscope has two opposed planar vibrating plates (14,24) which vibrate under buckling vibration mode and a second order bending vibration mode which is degenerated with or close to the buckling vibration mode. The gyroscope detects Coriolis force by detecting displacements in amplitude balance of the second order bending vibration modes generated when an angular rotation velocity around an axis parallel to surfaces of the vibrating plates is applied.
