摘要:
A vibrating gyroscope includes a vibrating body and at least one driving member located on the vibrating body. The at least one driving member is arranged vibrate the vibrating body in a direction that is substantially perpendicular to an axis of the vibrating body. At least two detection members are are arranged so as to be spaced from each other and operatively connected to the vibrating body. The at least two detection members are located on opposite sides of a plane which includes the axis and a vibrating direction of the vibrating body such that the at least two detection members detect vibration of the vibrating body at substantially the same amount and detect at a different amount a Coriolis force generated by a rotational angular velocity applied to the vibrating body.. A differential amplifier circuit is connected to the at least two detection members and is arranged receive signals from the at least two detection members and outputs a signal indicative of the Coriolis force by canceling detection signals received from the vibration body at the least two detection members.
