Summary:1. Field of the Invention An optical gyro is provided with a ring laser and detection unit for detecting the beat frequency of said ring laser, and comprises a first ring laser of which beat frequency decreases when the angular velocity increases in a certain direction from a standstill state and a second ring laser of which beat frequency increases when the angular velocity increases regardless of the rotating direction. The first and second ring lasers are so positioned as to be mutually independent optically.
