Acoustic Emission (AE) of optical fiber technology is a kind of advanced technology that present nondestructive detection puts forward, the fiber sensor has many advantages such as high precision immunity to electromagnetic interference, easily to realize distributive, real-time measurement, and so on, it will become the new development direction of nondestructive detection technology. In actual detection, in order to location AE source, we need to at the same time gather the AE signal of many passageways t...
