Distributed Sensing using Bi-Directional BOTDA System

A novel Bi-Directional Brillouin time domain analyzer (BD-BOTDA) is proposed and experimentally demonstrated by simultaneously detecting Brillouin signals over each half of the whole fiber at two wavelengths separately, achieving over 80 km sensing range with 2m spatial resolution.
