Paper Abstract

Sweep-free Brillouin optical time domain analysis (SF-BOTDA), which uses multi pump and probe tones for a much faster determination of the Brillouin frequency shift, has suffered from a trade-off between the required spatial resolution and the inter-tone frequency spacing. A new implementation of the technique, involving a novel sequencing of the probe signal with respect to the pump multi-tone pulse, together with advanced post-processing, removes this trade-off, allowing the method to achieve spatial resolutions comparable to those of classical BOTDA without sacrificing tone granularity. A spatial resolution of 2m is experimentally demonstrated.
