摘要：

Distributed static and dynamic sensing is demonstrated with an ultra-short fiber Bragg grating (USFBG) army. The USFBGs serve as the sensors and reflection mirrors at the same time. Distributed static sensing is performed by demodulating the strain-induced or temperature-induced wavelength shift of each USFBG. Dynamic vibration sensing is realized based on phase variation between two adjacent USFBG reflected pulses. Static temperature and dynamic vibration are applied to the sensing ultra-short FBG array simultaneously. The experiments show that the temperature measurement from 30 degrees C to 80 degrees C is achieved successfully. And dynamic sensing of ne scale vibration and 12.5 kHz acoustic wave are demonstrated at a sampling rate of 50 kHz.
