| Abstract(in English) | We propose and experimentally demonstrate a Brillouin optical correlation domain reflectometry system with double frequency modulation and phase modulation. Double frequency modulation onto the laser is used for expanding the measurement range, and phase modulation onto the reference lightwave is used for reducing background noise to enhance resolution and strain dynamic range. A section with 15 cm length and 7000 με strain was detected in 1250 m single mode fiber with 5.2 cm nominal spatial resolution. |
