摘要：
The principle and method of measurement and signal processing of the vibration for the structure by interferometric optical fiber sensor are described and vibration response property of the structure is measured under the free vibration with attenuation and vibration subjected to force in this paper. The measurement results by the optical fiber sensor and electric strain gauge are proximate, so this research provides a kinds of new method for real-time vibration monitoring of engineering structure.
