Abstract

Distributed optical-fiber sensing (DOFS) is a technique that utilizes the very special properties of the optical fiber to make simultaneous measurements of both the spatial and temporal behavior of a measurand field. 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 - 1m over a distance 100m, to an accuracy $OM1%. This paper summarizes the principles of DOFS, gives examples of systems which have been studied, and gives some indication as to what is in store for the future.
