Data from lab-scale experiments of fibre optic vibration measurement
Abstract
Understanding the exact nature of the coupling of the optical fiber in response to seismic waves in a variety of settings is key to quantitative interpretation and modelling of seismic data recorded by Distributed Acoustic Sensors (DAS). While field experiments are very useful for gaining understanding their interpretation is complicated by variations in the conditions along the fibre, such how “straight” the fibre is at a given location, and the properties of the surrounding material. Lab-scale experiment can be useful for investigating specific parameters, since they allow for precise control over the local conditions over short lengths of fibre. This activity works towards the establishment of a lab-scale test bed for characterizing fibre optic response to seismic disturbances Data from lab-scale experiments of fibre optic vibration measurement
