摘    要:光纤光栅传感器是一种新型传感器,有着非常广泛的应用前景。限制光纤光栅传感器大量实际应用的主要障碍是传感信号解调,因而,光纤光栅传感信号解调是光纤光栅传感器应用的关键技术之一。本文对现有已报道的光纤光栅传感信号的解调方法进行综述,并归类为:边缘滤波法、匹配滤波法、可调谐滤波法、光源波长可调谐扫描法、射频探测法、光栅啁啾法、CCD分光仪法、干涉法。对各种方法的原理及相关改进方法进行了阐述,并对其优缺点做了比较分析,最后,对光纤光栅传感信号的解调技术发展进行了展望。

关 键 词:光纤光栅传感器  信号解调  滤波法  干涉法

Abstract:Fiber Bragg grating sensor is a new kind of sensor , which has a very broad application prospect . The main obstacle to limit its wide application is signal demodulation .So the sensing signal demodulation for fiber Bragg grating is one of the key technologies for fiber Bragg grating sensor applications .The reported signal demodulation methods of fiber Bragg grating sensor are reviewed and classified into edge filter demodulation method, matched filter method , tunable filter method , tunable narrowband laser interrogation method , radio frequency signal measurement method , chirped FBG method , CCD measurement method , and interference method.The principle of various methods and some improved methods are elaborated , and their advantages and disadvantages are analyzed .Finally the demodulation technology for the development of fiber Bragg grating sensing signal is discussed .
Keywords:fiber Bragg grating sensor  signal demodulation  filter method  interference method
