Abstract :
A highly integrated optical fibre sensor for simultaneous discrete dynamic strain and distributed static strain/temperature measurements is experimentally demonstrated by combining Brillouin optical time domain analysis and time-division-multiplexed fibre Bragg grating (FBG) interrogation. A highly integrated sensor system is demonstrated by using a single laser source, one shared receiver block and broadband, low reflectivity FBGs.
