摘　　要：本文报导了一种实用型光纤光栅复用传感系统.该系统利用可调谐光栅反射解调的原理,其波长分辨率达到0.01 nm,对应测量的应变分辨率为8.27με.实用结果和理论值相吻合.A practival demodulation of multiplexed wavelength FBGs is proposed. The principle is based on the technology of the tunable fiber Bragg grating in the reflective mode. The detection wavelength of adjacent FBG and the wavelength resolution are discussed. Numerical and experimental results show that the wavelength resolution of measurement is 0. 01nm and strain resolution is 8. 27×10-6.
