Abstract:
A single-measurement sweep-free distributed Brillouin optical time domain analyzer (BOTDA) sensor is proposed and experimentally demonstrated employing digital optical frequency comb (DOFC) probe signal for coherent detection of Brillouin Phase Spectrum (BPS), without any frequency scanning and data averaging. The phase shift of each frequency tone induced by Brillouin interaction is simultaneously measured in a single data acquisition.
