| Abstract: | In civil engineering, the smart health monitoring method by use of fiber optic sensor is a new approach that evaluates the structural health situation. The systematic construction is described in this paper. The current status of application of fiber optic sensor to civil engineering both domestic and abroad is presented with some demonstrations, including the introduction of the classification,working principles and its characteristics. Displacement and Bragg grating fiber optic sensors are emphasized. Finally the paper points out the perspective usage and future studies of fiber optic sensing techniques in civil engineering. |
