Abstract:
A piezoelectric device, for use in a dual axial gyroscope system, comprising:piezoelectric exciter means shaped in plate disposed in a first plane, for generating a linear velocity;first piezoelectric detector means, placed on a surface of the piezoelectric exciter means and shaped in plate disposed in a second plane, for detecting a first Coriolis force provided in a direction orthogonal to the second plane, said second plane being orthogonal to the first plane; andsecond piezoelectric detector means, placed on the surface of the piezoelectric exciter means and shaped in plate disposed in a third plane, for detecting a second Coriolis force provided in a direction orthogonal to the the third plane, said third plane being orthogonal to both the first plane and the second plane.
