Device and system for detecting dynamic strain
A device and system for detecting dynamic strain. The device comprises a longitudinally extending carrier and an optical fiber embedded along an outer surface of a length of the carrier. The optical fiber comprises at least one pair of fiber Bragg gratings (FBGs) tuned to reflect substantially identical wavelengths. The system comprises the device and an interrogator comprising a laser source and a photodetector. The interrogator is configured to perform interferometry by shining laser light along the optical fiber and detecting light reflected by the FBGs. The interrogator outputs dynamic strain measurements based on interferometry performed on the reflected light.
