A new modulation and demodulation scheme for improving the performance of ring resonator gyroscopes is proposed. The method is compatible with out-of-resonance excitation of the ring, so relaxing requirements on control loop performance, and provides large immunity from changes in gains of optical and electrical paths. The separation of the carrier frequencies provides also intrinsic immunity from backscattering induced noise. In this paper, after the presentation of the method, numerical experiments are reported to demonstrate the correctness of the approach.

Abstract
A new modulation and demodulation scheme for improving the performance of ring resonator gyroscopes is proposed. The method is compatible with out-of-resonance excitation of the ring, so relaxing requirements on control loop performance, and provides large immunity from changes in gains of optical and electrical paths. The separation of the carrier frequencies provides also intrinsic immunity from backscattering induced noise. In this paper, after the presentation of the method, numerical experiments are reported to demonstrate the correctness of the approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
