Abstract

fast distributed Brillouin optical time domain analyzer (BOTDA) is proposed and experimentally demonstrated based on coherent detection of digital optical frequency comb (DOFC) probe signal. The phase shift of each frequency tone induced by Brillouin interaction, corresponding to the Brillouin Phase Spectrum (BPS), is simultaneously measured in a single data acquisition without averaging process. Based on coherent detection of BPS, single-measurement BOTDA sensor is demonstrated with a measurement time of 100 μs, with a spatial resolution of 51.2 m along 10 km fibre. Vibration frequency up to 1 kHz of dynamic measurement has been successfully observed.
