Abstract(in English) | We propose a novel method to improve the spatial resolution of Brillouin optical time-domain refiec-tometry (BOTDR), which is referred to as Synthetic BOTDR (S-BOTDR), and experimentally verify the resolution improvements Due to the uncertainty relation between position and frequency, the spatial resolution of a conven-tional BOTDR system has been limited to about one meter In S-BOTDR, a synthetic spectrum is obtained by combining four Brillouin spectrums measured with different composite pump lights and different composite low-pass filters We mathematically show that the resolution limit in principle for conventional BOTDR could be overcome by S-BOTDR and experimentally prove that 10-cm spatial resolution, which is much smaller than the conventional BOTDR limit, was attained by S-BOTDR |
