A method for monitoring of the deformations of components by means of optical fibers as well as optical waveguide for carrying out the method and a method for its production

摘要

In the process, the optical waveguides are mechanically pretensioned with respect to the component or in themselves to such an extent that for all the deformations to be expected in the component their stress remains within the tensile range. This results in the avoidance of compressions of the fibres of the optical waveguide which lead to undesired attenuation of the light pulses transmitted through the optical waveguide and corrupt the measurement result in connection with stress monitoring. …IMAGE…
