摘要：PROBLEM TO BE SOLVED: To provide a light-interference angular velocity meter wherein a psuedo-input summing circuit which gives a pseudo-input signal to an actual detection signal corresponding to an input angular velocity is provided, the repetition frequency of a sawtooth wave signal is increased temporarily or intermittently in the start or during the operation of the light-interference angular velocity meter, the stabilization time of a feedback signal amplitude control circuit is shortened and the stabilization time of a gyro output is shortened. SOLUTION: The light-interference angular velocity meter comprises a closed loop which controls the amplitude of the feedback signal of sawtooth waves. The angular velocity meter is provided-with the pseudo-input summing circuit 64 which gives the pseudo-input signal to the actual detection signal corresponding to the input angular velocity, and the repetition frequency of the sawtooth wave signal is increased.
