Based on the analysis on special preponderance of FBG sensing technology, in recent years, much research all over the world on FBG demodulation methods is introduced. Design and improvement of FBG distributing sensing system, development of inclination torque, and velocity of flow sensors are also introduced. At the same time,application example of health monitoring in the field of aviation industry and large-scale structure, bridge and main applications in the field of energy resource and chemical combination are summarized. Finally, difficulty and key problems occurring when FBG sensors come to practical applications are discussed. Its perspective development is also made.
