Abstract:
A vibrating gyroscope comprising:a vibrating body;at least one driving member located on said vibrating body and adapted to vibrate said vibrating body in a direction that is substantially perpendicular to an axis of said vibrating body;at least two detection members located spaced from each other and operatively connected to said vibrating body, said at least two detection members being located on opposite sides of a plane including said axis and a vibrating direction of said vibrating body such that said at least two detection members detect vibration of said vibrating body at substantially the same amount and detect at a different amount a Coriolis force generated by a rotational angular velocity applied to said vibrating body; anda differential amplifier circuit connected to said at least two detection members, the differential amplifier circuit receiving signals from said at least two detection members and outputting a signal indicative of said Coriolis force by canceling detection signals received from said vibration body at said at least two detection members.
