A distributed birefringence measurement of a polarization-maintaining fiber (PMF) can be realized by using a Brillouin dynamic grating (BDG). However, the pump depletion decreases the intensity of the BDG along the PMF and limits the measurement rang

Dynamic Brillouin optical fiber sensors based on fast scanning of Brillouin gain spectrum (BGS) are one of the most promising techniques to measure dynamic strains, where an ~11-GHz bandwidth arbitrary waveform generator (AWG) or a vector microwave g

Brillouin-based optical fiber sensing has been regarded as a good distributed measurement tool for the modern large geometrical structure and the industrial facilities because it can demodulate the distributed environment information (e.g., temperatu

A high-sensitivity distributed temperature sensor based on Brillouin scattering is theoretically proposed and experimentally demonstrated. Double-coated single-mode fibers (SMF) are used as sensing fibers to improve the temperature sensitivity of Bri
