Abstract
We analyzed the parameters and main noise influence on resonator fiber optic gyro’s finesse, and put forward the main way to improve the finesse. Then, we built the optical fiber ring resonator test system, inhibited the polarization fluctuation noise by using the polarization controller and polarization-laser, and at last took the backscattering noise tests. The experimental results showed that the inhibition of the polarization fluctuation noise has made the fiber optic resonant ring finesse increase from 64.67 to 84.57, resonant depth increase from 0.5033 to 0.7308. At the same time, we measured the intensity ratio of the Rayleigh backscattering light and main signal of 0.0267%. It provides a helpful reference for manufacturing of resonator fiber optic gyro.
