<p>An illumination system (10) for illuminating a scan region (42) on an object (14) may comprise a hollow reflector (46) having an interior reflective surface (54), an entrance aperture (56), and an exit aperture (58). A light source (44) is positioned adjacent the entrance aperture (56) of the hollow reflector (46) so that some of the light rays (50, 50') produced by the light source (44) pass through the entrance aperture (56) and are reflected by the interior reflective surface (54) of the hollow reflector (46) before passing through the exit aperture (58). <IMAGE></p> |
