Abstract

In order to improve the overall performance of reflective intensity modulation fiber optic acoustic sensor, the fiber-optic sensing probe was optimizing designed. Through constructing experimental platform, the sensitivity and frequency characteristics of the sensor were tested. The experimental results suggest that the sensor's sensitivity is found to be 550mV/Pa, and the measurement range lies within 50Hz ~ 10000Hz, which meets the requirements of the project indicators. Meanwhile experimental results show that the structure of fiber-optic sensing probe is simple reasonable designed and has strong practicability.
