Abstract
For Brillouin Optical Time Domain Reflectometry (BOTDR) based distributed sensing technique, limited by 1m-order spatial resolution, it is difficult to monitor or test localized deformation, and loop installation of optical fiber sensors is a good countermeasure, In this paper, firstly, the measurement behavior and performance of loop installed optical fiber sensors is investigated experimentally, and the accuracy of BOTDR based distributed fiber optic sensors (DFOS) is evaluated. Furthermore, an experimental investigations on a steel specimen is carried out. Based on the investigations, steel structure damage identification method with no requirement for a structural Numerical Model is proposed.
