Stimulated Brillouin scattering (SBS)-based distributed fiber optic sensing technique has found pervasive applications in measurement of real-world environmental variables. Its sensing capability, …
A co-propagating dual-wave interferometer- assisted Brillouin optical time domain analysis (DWI-BOTDA) integrated sensing system is proposed and experimentally demonstrated for high sampling rate d…
An approach of phase-shift transform is proposed and demonstrated to suppress the interference fading in phase sensitive optical time domain reflectometry (Φ-OTDR). The phase-shift transform is ex…
A Brillouin phase spectra (BPS) demodulation approach in Brillouin optical time-domain analysis (BOTDA) based on phase to intensity conversion is proposed and demonstrated. By utilizing the cascade…
