Research progress based on FBG burst pressure detection

Due to its advantages in sensitivity, insulation, corrosion resistance and distributed measurement, optical fiber grating pressure sensors have been gradually paid attention to in the fields of energy, chemical industry, aerospace and civil engineering. This paper firstly introduces the principle of fiber optic grating sensor, then some research hotspots of fiber grating sensors are reviewed, emphasize on the application and research of FBG sensor in boom pressure measurement, and finally summarizes the difficulties and technical development direction.
