Intensity Demodulation Based Fiber Sensor for Dynamic Measurement of Acoustic Wave and Lateral Pressure Simultaneously

In this paper, we propose an intensity demodulation based fiber sensor for dual-parameters sensing of acoustic wave and lateral pressure. The sensor consists of a long period fiber grating (LPFG) inserted into a Sagnac interferometer (SI). The LPFG is kept straight and fixed on a polyethylene tereph...
