Abstract

Time-domain distributed Brillouin sensing with a spatial resolution of 2 cm and 12,000 resolving points is experimentally demonstrated through a time expansion scheme. Two combs with different line spacing serve as the probe and pump, respectively, and the acoustic phonon information generated by their spectral beating is down-converted to a detection bandwidth of less than 100 kHz. © 2023 Jae Hyeong Youn, Kwang Yong Song, Sonia Martin-Lopez, Miguel Gonzalez-Herraez, and Maria R.
