Recording the state of infrastructure is essential for maintaining bridges, dams and tunnels. Measuring the strain in buildings allows to predict nature and grade of local loads. Fibre Bragg gratings are used besides fibre optic communications for strain and temperature sensing. For this the long-term stable application of the gratings and an interrogation of changes in the Bragg wavelength are the main problems.
