| 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. |
