Abstract

Distributed fibre optic sensing (DFOS) is a versatile measurement technology, especially useful to monitor linear structures including road infrastructure. It allows measuring strains, displacements or temperatures continuously in a geometrical sense, so all local events (e.g. cracks or sinkholes) can be detected directly. The article summarises the newest achievements related to composite and monolithic DFOS sensors created especially for civil engineering and geotechnical applications. The design of the sensors supported by theoretical background and practical applications are discussed in relation to road embankments and asphalt layers. These successful applications of composite and monolithic DFOS sensors are the first of such types in the world.
