This paper proposes a new approach to detecting bolts' anchoring qualities based on the fiber Bragg grating sensing principle. Basically, Fiber Optic Bragg Sensors are strain-measuring devices and therefore provide many of the advantages of the well known metal foil strain gages. This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which.
