ABSTRACT:
An illumination device includes a light source for supplying light, an optical system for forming plural light fluxes from the light supplied by the light source, a scanning system disposed to receive the light fluxes formed by the forming optical system and for scanning the light fluxes substantially at the same time, and another optical system effective to superimpose the scanned light fluxes upon one another on a surface to be irradiated.
