| Abstract: | This paper first introduces the applications of fiber sensors and the structure of S-shaped fiber Acoustic Emission(AE) sensors.Then,it presents the interactions between the fiber AE sensor and ultrasonic waves and the theoretical analysis of the sensitivity of this type of sensors that are based on fiber Michelson interferometer.The result of the analysis is identical with that by Matlab simulation. |
