Abstract

When the method of dual 90-degree rotation splices in the resonator is used to suppress the zero-bias drift caused by polarization noise of the RFOG, the asymmetry of the two 90-degree rotation splices will cause the Shupe effect error. The mathematical model of the Shupe effect caused by the asymmetry of two 90-degree rotation splices is established and simulated in this paper. The simulation results show that the value of the Shupe effect error is proportional to the asymmetric length of the two 90-degree rotation splices. The Shupe effect error can be suppressed by reducing the asymmetric length.
