Frequency-distortion-suppressed phase-sensitive OFDR by using dual-wavelength digitally enhanced interferometry
We report on a phase-sensitive optical frequency domain reflectometry that allows for frequency distortion suppression in distributed sensing by using dual-wavelength digitally enhanced interferometry. Preserved sensing performance for a strain precision of 0.1 με/√Hz with a sensing spatial resolution of 1.25 m along 4.6 km has been verified in the presence of both environmental and artificially induced frequency distortions, testifying the effective frequency distortion suppression.
