The gyro zero drift caused by the polarization error is theoretically deduced by the matrix method, and the theoretical simulation is carried out by computer simulation. Secondly, the choice of the light source of resonant fiber optic gyroscope system is analyzed, and the effect of the light source linewidth on the fiber loop resonance curve Finally, the detection scheme of FOG and the development trend of FOG are analyzed. Resonance fiber optic gyroscope system is analyzed from the aspects of noise factor, device selection and signal detection, which provides theoretical and experimental basis for the construction of resonant fiber optic gyroscope system.
