Acoustic Emission Sensor

The crack is easily generated in the metal structure because of fatigue. It has a strong impact on structural safety. To reduce accident and losses, it is important to detect the local damage such as active crack. The general method to detect the local damage is acoustic-emission technique. But it has the disadvantages of short distance transmission, interfered easily and so on. In this paper, the fiber optic acoustic emission sensor system is designed and developed. A lot of experiments have been done in laboratory. It is shown that the new system has long distance transmission, and has high anti-interference etc. It can meet the demand of local damage detection about the metal structure.
