TY - CONF A1 - Hicke, Konstantin T1 - Distributed Fibre Optic Sensing for Monitoring and Testing of Industrial and Civil Infrastructures N2 - Fibre optic sensors enable the gathering of sensory information in environments where conventional sensors fail or simply can not be utilised. Their small size enables their use in confined spaces as well as their embedding or integration in components, structures or composite materials while offering, depending on the approach, high sensitivity, very high spatial resolution and, especially, the possibility to detect or measure physical quantities in a distributed way, meaning spatially continuous sensing over very long distances. Those distributed fibre optic sensors (DFOS) provide access to sensing information from different locations along the sensing fibre without the need for technologically challenging multiplexing of many point sensors and the subsequent sensor data fusion. In this way, DFOS are excellently suited as smart sensors for monitoring or testing purposes as the spatially distributed sensing data make available spatially resolved measurand profiles without a gap. Furthermore, the possible embedding or integration of DFOS could facilitate the development of smart structures or smart components. In particular distributed vibration sensing (DVS) and distributed temperature sensing (DTS) are also ideally suited for condition monitoring of machinery, industrial installations or extensive infrastructure, also, on-line real-time assembly or component testing in production lines, e.g. for quality control, is possible. In this talk, we will shortly outline the underlying principles of some fibre optic sensing approaches, explain their fundamental differences in mode of operation and performance, and discuss their applicability and limitations. Moreover, we will report on a subset of current and previous applied research projects at BAM, investigating different areas of use for distributed fibre optic sensors in particular.
