Research progress in signal demodulation technology of fiber Bragg grating sensors
摘要
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 sig-nal 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 .关键词
