摘　　要：基于光纤传输技术,设计并开发了一种新型的非本征型光纤传输声发射局部损伤监测系统,并对试样进行了声发射信号的监测试验。结果表明,带光纤的传感器具有传输距离远、抗干扰能力强等优点,可较好地满足大型设备局部损伤监测的要求。In this paper, the local damage monitoring system which is based on extrinsic fiber optic acoustic emission is designed and developed. Some experiments have been done in laboratory. It is shown that the new system is capable of long distance transmission, and has high anti-interference etc. It can meet the demand of local damage monitoring about the large equipment.
