Abstract
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. 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. Measurement of spatial distributions with a resolution 0.1 - 1 m over a distance 100m, to an accuracy approximately 1%, may be expected. 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.
