Vibratory gyroscope

摘要

Described herein is a vibratory gyroscope. In the present vibratory gyroscope, two detection output portions are provided on a vibrator. The detection output portions are constructed such that an output (corresponding to a null output F0) obtained when no angular velocity is given, can be produced in phase and Coriolis output components F omega C and F omega D can be outputted in phase opposite to each other. Outputs C and D produced from both detection output portions result in the sum of vectors represented as F0 and F omega C and the sum of vectors represented as F0 and F omega D respectively. However, the sensitivity of detection of Coriolis force components can be increased by determining the difference phi in phase between the detected outputs C and D.
