摘要:
The present invention relates to a method for producing light-scattering elements by holographic illumination of a layer (10) of a photo-sensitive material on a support plate (1) and subsequent development of the layer (10) in order to generating a surface structure. The method is distinguished in that the illumination occurs using at least two mutually coherent luminous beams (2,3) which have passed through one or a plurality of primary diffusers (8,9) respectively were reflected at one or a plurality of primary diffusers, the luminous beams (2,3) being irradiated from different directions and being at least partially superimposed on the layer (10) while forming an interference pattern. This method permits producing diffusers having a leveled scatter profile in a simple manner.
