| Abstract(in English) | The receiver sensitivity of the double-pulse BOTDR was improved by 7 dB by shifting frequency band for the Brillouin scattered light detection from a microwave band around 11 GHz to the baseband Thanks to this improvement, the measurement range was extended from several tens meters to 2 km We achieved one-end access distnbuted Bnllouin frequency shift measurement with a spatial resolution of 20 cm and an error (σ) of 0 50 MHz over a 2-km long fiber The measurement range is limited by the self-phase modulation the double-pulsed light suffers in the fiber, and its further extension is possible by improving the pulse waveform |
