Abstract.
A frequency-sensitive optical gyroscope based on an electro-optical oscillator is proposed. The operating principles of this device are described, its noise and ultimate sensitivity are estimated. The proposed gyroscope is self-oscillating device whose operating frequency is changed as a result of a change of the rotation rate but one is entirely free from the problem of locking.
