Paper Abstract

A novel single-ended distributed fiber sensor based on stimulated Brillouin scattering (SBS) with high spatial resolution is proposed and experimentally validated. This single-ended technique is based on modulated optical long pulse that consists of two sidebands. The probe wave is obtained by an attenuator and Fresnel reflection. The spatial resolution is only limited by the fall-time of the long pulse without secondary "echo" phenomena. In addition, the configuration of this single-ended technique is very simple and has no need to spend extra measurement time compared with conventional BOTDA.
