Paper Abstract

An approach has been developed for real-time vibration monitoring of a composite cantilever beam. The fiber Bragg grating (FBG) sensor has an advantage to be embedded or bonded to the structure compared with other sensors such as piezoelectric sensor or strain gage, thus allowing the measurement of parameters like strain and temperature. In this paper the vibration sensor system with a FBG embedded in a composite smart structure is proposed. This system can assort vibration direction and sensing vibration amplitude just by measuring output voltage. The sensing resolution is decided by the slope of the filter used in the system.
