摘　　要：在各种光纤传感器中,光纤Bragg光栅(FBG)传感器是近几年来研究的热点。研究光纤光栅传感器的关键问题是光纤光栅的信号解调,即波长微小移位的检测问题。概述了光纤光栅传感器解调原理,并从响应特性分类角度对光纤光栅的几种解调方法进行了分析比较。In recent years, the fiber Bragg grating （FBG）sensor is a research hotspot concerning about optical fiber sensors. The key problem of FBG sensor study is the optical fiber diffraction grating signal demodulation, namely, the detection of small shifting of wave length. The demodulation principle of FBG is outlined, and several demodulation methods are analyzed and compared frnm the classification of response characteristics.
