The volume of research on distributed optical fibre vibration sensors, also known as distributed acoustic sensors (DAS), has increased substantially in the recent years. DAS systems owe their rising popularity to their capability of mapping vibration

A novel subsea cable condition monitoring technique based on embedded optical fiber inside the cable is demonstrated. It is shown that a distributed optical fiber vibration sensor can be used to map dynamic strains all along the cable simultaneously.

Existing sensing technologies lack the ability to spatially resolve multiple sources of water or humidity without relying on the deployment of numerous inline sensors. A fully distributed approach has the potential to unlock a diverse range of applic

A distributed vibration sensor is used to measure vibrations along a subsea power cable. It is shown that the DVS is capable of mapping vibrations along a 10km-long subsea power cable with perturbation frequencies as low as 0.1Hz.

A portable distributed vibration sensor is developed to assess the feasibility of monitoring the mechanical stresses in subsea-cable. It is shown that the sensing unit is capable of mapping dynamic perturbations and impact along a 10km-long subsea po

A distributed optical fibre acoustic sensor is numerically modelled. To increase the flexibility of the model, the building blocks of the sensing system are modelled separately and later combined to form the numerical model. This approach is adopted

A Distributed Vibration Sensor Based on Phase-Sensitive OTDR is numerically modeled. The advantage of modeling the building blocks of the sensor individually and combining the blocks to analyse the behavior of the sensing system is discussed. It is s

A distributed optical fiber dynamic strain sensor with high spatial and frequency resolution is demonstrated. The sensor, which uses the ϕ-OTDR interrogation technique, exhibited a higher sensitivity thanks to an improved optical arrangement and a n

A distributed optical fibre sensing system is studied which uses a PZT to modulate the phase of the backscattered Rayleigh light in order to enhance the frequency range and strain sensitivity of the sensing system.
