摘　　要：A novel micro resonator optic gyroscope comprising a dual-resonator structure is proposed.This design radically eliminates the noise induced by Rayleigh backscattering,the Kerr effect and polarization coupling.The configuration of the micro optic gyroscope(MOG)is given and described.Three methods are applied to suppress the optical noises in the system and to theoretically analyze the performance improvement.Experiments are carried out on both dual-resonator and single-resonator MOGs,which show the resonance depth improvement from 0.7477 to 0.9173 in the present MOG dual-resonator configuration.
