Polarimetric distributed optical fiber sensing
Distributed optical fiber sensing (DOFS) is a technique which utilizes the very special properties of the optical fiber to make simultaneous measurements of both the spatial and temporal behavior of a measurand field [1, 2]. As such, it provides an extra dimension in the measurement process, leading to finer monitoring and control, and to a new level of understanding, especially in regard to the behavior of large structures. Thus, we may expect to measure spatial distributions with a resolution 0.1–1 m over a distance of 100 m, to an accuracy of ~1%.
