Paper Abstract

Distributed optical-fiber sensing promises to be a powerful technique for the monitoring and diagnosis of large structures. The technique provides the means by which the spatial and temporal distribution of, for example, strain and temperature can be measured, with good accuracy, throughout the structure. Backscatter methods in fibers are limited, in the performance which they can provide, by a low signal level. Better performance can be achieved by using forward-scatter methods which use polarimetric techniques and/or nonlinear optical effects. Such methods are reviewed in this paper and three of them are described in detail. Prospects for application are very promising.
