Paper Abstract

We proposed and experimentally demonstrated a distributed optic-fiber sensor based on the Raman loop configuration and fiber loss characteristic for detecting the temperature and structure's crack. Among them, the Raman loop configuration with reference fiber is proposed to detect the temperature profile along the sensing fiber. It can eliminate the influence of external physical perturbation on the temperature measurement results, and don't require pre-calibration process before measurement. This proposed method improves the engineering applicability of optic-fiber sensors. In addition, the information of crack is detected by using the fiber loss characteristics based on OTDR technology.
