Abstract:This paper introduced the distributed optical fiber sensing technology which is based on Raman scattered light theory. It discusses the technology in the following aspects: basic working principle, structure, system characteristics and signal handling. This kind of structure and signal handling method had a certain spatial resolution and hence ensure practicability of the system.
Keywords:optical time-domain reflectometer (OTDR)  distributed optical fiber temperature sensor  Raman scattering  Stokes scattered light  Anti-stokes scattered light  Multi-resolution analysis  Wavelet
