Abstract: A strain measuring device includes a first sensing optical fiber disposed on a surface of a measurement target. A second sensing optical fiber is spaced apart from the first sensing optical fiber and arranged parallel to the first sensing optical fiber. The second sensing optical fiber is spaced apart from the surface of the measurement target. An optical fiber guide has an inner cavity. The optical fiber guide is bonded to the surface of the measurement target to be positioned on the surface of the measurement target. The second sensing optical fiber is disposed in the inner cavity. A controller receives measured values from the first sensing optical fiber and the second sensing optical fiber. The first sensing optical fiber and the second sensing optical fiber include optical fibers for measuring strain.
