Strain and temperature simultaneous measurement in kilometer-scale fiber-optic gyroscopic coils using OFDR
In this paper, a delay correction method is proposed to overcome the Rayleigh backscattering (RBS) spectra mismatch between orthogonal polarization axes caused by birefringence delay, thus extending measurement distance. In the experiment, the strain and temperature simultaneous measurement of the 3 km fiber-optic gyroscopic coil is realized at a spatial resolution of 5 cm. This research provides a crucial basis for the performance evaluation of fiber-optic gyroscopes.
