摘　　要：提出一种新的利用共振原理对微振动放大进行测量的光纤振动传感器 .光纤振动不受强电磁场和温度变化影响 ,可用于大型发电机 ( 30 0mW )定子端部绕组微振动的在线测量 .实验结果表明该光纤振动传感器可以达到相当高的精度 ,对解决特殊环境下微振动的实时监控有重要应用价值 .A novel type of optical sensor is designed, whose principle is based on resonance of optical fiber. This sensor can detect the vibration of 10 -5 m level. It isn′t subject to strong electromagnetic field and temperature variation. It′s suitable for real time supervision on stator end-winding of generator(300 MW). With this novel sensor, the life of normal generators can be well elongated.
