We are oriented to research, development and to methodology of the production and application of FBGs. The elongation of FBGs can calculated from frequency drift of the Bragg resonance wavelength and from the change of the grating period during stretching. The inhomogeneity of optical fibers and of the FBGs can induce change of the grating period (Bragg resonance wavelength) of FBG which can be nonlinear with elongation of the optical fiber with FBG. Setup of the measurement of elongation of FBGs is in Fig. 1. The calibration of FBGs will be used for preparation and for the realization of the technology of measurement of shape deformation of concrete buildings.
