Abstract
A distributed optical fiber sensor for sensing physical characteristics of an object, such as strain, includes several discontinuities, each pair of discontinuities being placed at one specific location on the object. A laser beam is past through the fiber and the discontinuities generate components from the beams having parameters indicative of the respective physical characteristics. The components combine in a composite beam which is detected outside the beam and separated into the respective components.
