  • Patent number: 4926040
    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.

  • Patent number: 4370026
    Abstract: Illuminating device comprising a laser source providing a coherent beam with gaussian distribution of intensity and means for separating the initial beam into four parts along two orthogonal directions, means for recombining the four parts resulting in their partial superimposition in a predetermined plane and means for averaging the interferences produced in the plane by the four parts.
