Vibrating gyroscope and treatment process

摘要

A vibrating gyroscope has a base and a resonator. The resonator includes a body of generally cylindrical shape terminating in a face. The resonator is capable of vibrating according to a first vibration mode having antinodes distributed on n axes, and a second vibration mode having antinodes distributed on n other axes. The face of the resonator has two piezoelectric assemblies on each axis of the first and of the second vibration modes. Each piezoelectric assembly has at least one piezoelectric element capable of exciting the resonator in vibration and at least one piezoelectric element capable of detecting vibrations of the resonator at the same time.
