ABSTRACT:
In a laser gyroscope it is desirable for precision operation to eliminate or effectively compensate temperature variations, as well as manufacturing tolerances. To this end the present laser gyroscope has two ring lasers physically arranged so close to each other that there is an optimal thermic contact between the two ring lasers. Temperature sensors are arranged in contact with the resonator circumference to control a piezoelectric resonator tuning device in response to temperature variations to compensate the same. The modulators of the lasers are periodically switched, for example, with the aid of Faraday cells to reverse the travel direction of the travelling waves to thereby compensate for manufacturing tolerances, and any remaining temperature variations.
