  • Apparatus for detecting changes of length in a medium employing different fiber length
    Patent number: 5148017
    Abstract: Apparatus for detecting changes of a medium along a measuring path in the medium, comprising several lightwave conductors arranged on a carrier, conveniently in a sleeve. Reflective ends of the light wave conductors are fixed at different distances along the measuring path. Type, extent, and location of longitudinal changes in the medium to be checked can be detected at any time by optical length measuring of the individual lightwave conductors by means of an optical rangefinder.

  • Method for monitoring deformations with light waveguides
    Patent number: 5044205
    Abstract: A method for the monitoring of deformation of components with light waveguides which are connected securely to the component at least over part of the length of the latter and are connected to a measuring apparatus with which the transmitting capacity of the light waveguide and the transit time and/or the damping of the light pulses sent through the light waveguides are continuously or intermittently monitored. The light waveguides are prestressed such that they remain in tension at all levels of deformation expected.
