Analysis of the properties of measuring elongation systems using uniform Bragg gratings as measuring transducers

摘要

The paper presents the analysis of the influence of elongation of stainless steel and aluminium samples on the response of uniform fiber Bragg gratings used as measuring transducers. Research indicates the possibility of material type and material thicknessing on the basis of transmission spectra obtained with the use of a periodic structure. During the research, deformations of transmission spectra were noticed. These defects may be the result of the glue connection used for assemble the periodic structure to the sample. The results of the research were presented in the form of charts obtained on the basis of transmission spectra.
