Abstract
In a ring resonator gyro the CW and CCW beams are modulated to provide each with a spectrum including a carrier and an upper and a lower side band. The upper side band of one beam is kept at a resonance by a path length control loop 24 and the upper side band of the other beam is kept at a resonance by a rate control loop 40.
