摘要
利用啁啾光纤光栅结合长周期光纤光栅边沿线性滤波技术 ,提出了一种新颖的光纤光栅传感解调方法 ,并实现了在传感波长变化 5nm范围内的波长解调 采用了全光纤结构 ,无需机械部件调谐 。
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.
