Paper Abstract

A temperature-compensated strain-sensing sensor based on fiber Bragg gratings (FBGs) that is suitable for strain mapping of rock in coal exploring application is demonstrated. FBGs were bonded to carbon fiber laminated composite (CFLC) and they were arranged in a FBG rosette configuration used to determine the direction and magnitude of the principal strain, information that is required for strain mapping. An extra reference grating was utilized for temperature compensation measurement.
