Abstract

The article presents the possibilities of detecting defect in materials using the fiber Bragg gratings (FBG). Steel belts with a thickness of 1 mm were used for the tests: one standard and the others were damaged. The damage was in the form of incisions. The FBG was glued to the sample with epoxy glue along its entire length and elongation by outside force. Based on the transmission spectrum obtained on the Optical Spectrum Analyzer (OSA) the processing characteristics: the main minimum on the transmission characteristics, total width of the spectrum and the full width at half maximum FWHM depending on the FBG strain was determine.
