Optical elements for illumination systems in different display screens (including 3D displays) and generating the radiation patterns of LEDs are considered. It is analyzed in which way the intensity distribution and the light scattering indicatrix are affected by the ratio of the height dispersion and the correlation length of surface roughness, the coherence radius of incident light, and the refractive index of the diffuser material. It is shown that the light scattering indicatrix is narrowed with increasing correlation length of the film surface roughness and/or the radius of radiation coherence.
