Seeking a low-cost and high-performance demodulating method of fiber Bragg grating(FBG) sensing system is one of the key techniques for FBG sensor to enter a practicable step.The general sensing principle of FBG sensor is introduced.Several demodulating methods advanced in inner and foreign country are presented.The operational mechanism and performance are analyzed and compared.Finally
the advantage and disadvantage of the signal demodulating methods are summarized and the development direction in signal demodulation of FBG is indicated
the foundation for the design of FBG sensing demodulation system is provided.
