介绍一种采用光纤Ｆａｂｒｙ－Ｐｅｒｏｔ干涉原理实现对ＡＥ波检测的传感器，其振幅的分辨率高达埃级（１０~(－１０)ｍ），频带扩展到 １．４ＭＨｚ，且具有良好的测量稳定性和可靠性．
A sensor based on fiber Fabry-Perot interference principle for detecting AE waves is introduced. The resolution of the amplitude is up to A (10 ~ (-10) m), the frequency band is extended to 1.4MHz, and has good measurement stability And reliability.
