Abstract:
1. An illumination system, comprising: a variable intensity illuminator lens comprising a generally elongate transparent body, said generally elongate transparent body having a light input surface and a light output surface, said variable intensity illuminator lens having a first converging power at a first position on said generally elongate transparent body and a second converging power at a second position on said generally elongate transparent body, the first converging power being different from the second converging power; a first light source positioned adjacent the light input surface of said variable intensity illuminator lens; a cylindrical lens positioned adjacent said variable intensity illuminator lens so that said cylindrical lens and said variable intensity illuminator lens extend along a lengthwise direction; and a second light source positioned adjacent said cylindrical lens, said variable intensity illuminator lens directing light from said first light source to a remote target region on an object, said cylindrical lens directing light from said second light source to a proximate target region on the object.
