Tsuda et al [2006] have studied damage detection of CFRP using Fiber Bragg Grating (FBG) sensors. Murayama et al [2000] have studied SHM of a full-scale composite structure using fiber optic sensors. Xu et al [2003] have introduced an approach for delamination detection using fiber optic interferometric technique. Tennyson et al [2001] have described the development and application of fiber optic sensors for monitoring bridge structures. Chan et al [2002] have investigated the feasibility of SHM using FBG sensors via monitoring of the strain of different parts of a suspension bridge. FBG strain sensors are developed by Moyo et al [2005] for SHM of large scale civil infrastructure. Ling et al [2004] have studied the dynamic strain measurement and delamination detection of composite structures using embedded multiplexed FBG sensors through experimental and theoretical approaches and revealed that the embedded FBG sensors are able to actually measure the dynamic strain and identify the existence of delamination of the structures. Li et al [2004] have presented an overview of research and development in the field of fiber optical sensor based SHM for civil engineering applications including buildings, piles, bridges, pipelines, tunnels and dams. Cusano et al [2004] have described the design of a FBG sensing system for static and dynamic strain measurements leading to the possibility to perform high frequency detection for on-line SHM in civil, aeronautic and aerospace applications.
