Abstract
A method for producing light-scattering structures on flat optical waveguides into which light can be coupled for making the light-scattering structures visible. The light-scattering structures are applied to a surface of the optical waveguide in accordance with a predetermined arrangement prescription. The light-scattering structures are applied directly to the optical waveguide with a non-impact method. The application of the light-scattering structures can occur by imprinting with a computer-controlled, contactless-operating print head or by electro-photographic coating.
