ABSTRACT:
During an initial pressure application on a light waveguide with a coating, which waveguide is subjected to a flexional coupling, deformation of the coating will occur and the value of an outfed light from the light waveguide will change as the deformation changes. The final intensity of the outfed light is obtained during the deformation of the coating by a process of extrapolating the final value from the initial measured values occurring during the initial deformation of the coating.
