The mechanism of fiber coil polarization properties’ effect on the performance of a fiber optical gyroscope (FOG) is investigated with analysis of secondary wave trains’ polarization evolution and interference in the fiber coil. Based on the optical model, the simulation demonstrates that the bias error varies nonlinearly with the fiber coil polarization crosstalk, and the experiment verifies the analysis and simulation result, so some measures are promoted to reduce the bias’ dependence on the fiber coil’s polarization properties, which is significant for improving environmental adaptability and long-term stability of the FOG.
