Abstract: A ring laser gyroscope includes an optical block for generating laser beams that counter-propagate in a closed-loop type optical path, a dither mechanism for applying dither vibration for mitigating a lock-in phenomenon to the optical block, and a dither controller for controlling the dither vibration. The dither controller imparts randomness to the frequency of the angular velocity of the dither vibration.
