The structural strain measurement of tension and compression in a 4m long concrete beam was demonstrated with a distributed fiber-optic sensor portable system based on Brillouin scattering. Strainmeasurements provided by the fiber-optic sensor permitted to detect the formation of a crack in the beam resulting from the external applied load.

Abstract

The structural strain measurement of tension and compression in a 4m long concrete beam was demonstrated with a distributed fiber-optic sensor portable system based on Brillouin scattering. Strainmeasurements provided by the fiber-optic sensor permitted to detect the formation of a crack in the beam resulting from the external applied load. The sensor systemis valuable for structural monitoring applications, enabling the long-term performance and health of structures to be efficiently monitored.
