Abstract
To provide a compact and high performance gyroscope. A gyroscope () comprises an outer frame (); an inner frame () positioned inside the outer frame and supported to be movable in one reciprocating direction; a plurality of proof masses () positioned inside the inner frame and supported to be movable in the direction orthogonal to the one reciprocating direction; a plurality of outer support suspensions () which connect the outer frame and the inner frame; a plurality of inner support suspensions () which connect the inner frame and each of the proof masses; actuators () for accelerating each of the proof masses; and detectors () for detecting displacement of the inner frame against the outer frame. The actuators oscillate the plurality of proof masses in-phase, and wherein Coriolis forces induced on each of the proof masses are summed up in the inner frame.
