Abstract
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.
