Distributed optical fiber sensing technology has a relatively wide application It canlocate and monitor the acoustic emission source in long-distance, large-scale.but also canreal-time, on-line, dynamic monitor the damage of the structural and the material and locatethe position. In civil engineering, if distributed optical fiber sensors can be successfullyapplied, it will bring huge economic benefits.This topic is study on distributed optic fiberacoustic emission sensor.
This paper introduces the devel...
