ABSTRACT:
Disclosed is a shift sensor with birefringent optic fiber, wherein two fixed coupling points are provided. One movable coupling point, created by a coupling means, for which it is sought to measure the shift gets shifted over the fiber. A source emits a plane polarized wave along a neutral axis of the fiber. A coupled wave train is created at each coupling point. These coupled wave trains have a propagation speed which is smaller than that of the primary wave train. A detector enables the locating of the relative positions of the coupled wave trains and, hence, of the movable coupling point with reference to the fixed coupling points.
