In this work, a low cost optical fibre sensing system for concrete cracks assessment inside a road tunnel is presented. A plastic optical fibre, with large dynamic strain range is used for sensing cracks. The system exploits a commercially available interrogator capable of estimating integral deformation of the cable via a phase measurement of a RF modulated optical signal.

Abstract
In this work, a low cost optical fibre sensing system for concrete cracks assessment inside a road tunnel is presented. A plastic optical fibre, with large dynamic strain range is used for sensing cracks. The system exploits a commercially available interrogator capable of estimating integral deformation of the cable via a phase measurement of a RF modulated optical signal.File in questo prodotto:
