| Abstract: | A new demodulation method for fiber Bragg grating sensing signal,which uses the edge of linear filter of an amplified spontaneous emission(ASE) light source,is designed and realized.Using this method the linear demodulation with a bandwidth of 3 nm is achieved.This high-speed demodulation system is an all-fiber system.The advantages of this system are rapid response and high ratio of cost performance.The strain measuring range is about 2 500 με. |
