Paper Abstract

This paper gives a brief description of a method to calculate the light-engineering criteria of anti-fog headlight performance under different atmospheric aerosol environments featuring by coarse composition of particles. This method uses the modified small-angle diffusion approximation and aspect-invariance principle to treat the highly forward-extended phase functions of aerosols and rather an intricate angular pattern of the light source. Some exemplary results are presented to illustrate the limiting visibility range of road objects illuminated by anti-fog headlights under snow, dust, rain, and fog conditions.
