一种利用啁啾光栅反射滤波的光纤光栅传感解调方法

A novel method of the demodulation of fiber Bragg grating sensing system based on chirp grating and LPG edge filter linear demodulation techique is presented. Using this method based intensity,the demodulation of fiber sensing system with a bandwidth of 5 nm is achieved.It is an all-filber design, quasistatic and dynamic operation, and potential high-speed demodulation system.
