Fiber Bragg gratings embedded inside glued laminated timbers: an overview and evaluation

Original language description

In this paper, the fiber Bragg gratings are investigated in the context of sensing of deformation inside a sample of a glued laminated timber. For this purpose, a fiber with acrylate recoated Bragg grating is placed and glued between the timber laminates. Since there are still some open questions leading now, one of the goals is to specify, if the sensor that is embedded inside the timber can operate as the sensor that is not. Therefore, the strain of the not embedded sensor is numerically investigated in the first step as the change in the grating period. In order to calculate the Bragg wavelength associated to the grating period, the light propagation through the fiber has been modeled by rigorous and versatile eigen mode expansion method. Based on the simulation result, the authors are able to determine the sample strain under the mechanical load by measuring the reflected Bragg wavelength. Moreover, the measured strain is compared with the strain analytically obtained from the known force applied on the sample. The both strains are in good agreement.
