摘　　要：将光纤光栅传感技术与液体的声光效应相结合,实现对液体浓度的检测。由于液体浓度的变化,光声效应产生的声信号将发生变化,利用光纤光栅声传感技术识别声信号的变化情况,从而实现对液体浓度的检测。实验结果验证了该方法的可行性,该方法对液体浓度测量的灵敏度可达0.05%/mV。Liquid content measurement can be implemented by fiber Bragg grating sensor together with photo-acoustic effect. The feasibility of using fiber-optic sensor to detect underwater sound signals are analyzed which is created by photo-acoustic effect. Fiber Bragg grating sensor is used for underwater sound signals measurement, and then the liquid content is detected. Preliminary experimental results indicate the feasibility, and the accuracy is 0.05%/mV.
