Abstract
In this paper, the sensing behavior of the pulse-prepump Brillouin Optical Time Domain Analysis (PPP-BOTDA) based distributed sensing technique with a 0.1m-order spatial resolution is experimentally studied, and the sensing features of different types of fiber optic sensors (FOSs) are compared. Based on experimental results, we found that slippage occurred between bare fibers and coating materials, and that a different FOS type has a different degree of slippage. Despite possessing 10cm-order spatial resolution, if the gauge length of FOS is shorter than the critical effective sensing length (CESL), the measurement accuracy is significantly affected by the slippage. In order to enhance the sensing performance of FOS, a packaging design for the practical adaptation of no-slip FOS for structural health monitoring applications is proposed. Finally, the performances of packaged optic fibers isare experimentally verified.
