Abstract
An illumination system for illuminating a scan region on an object may comprise a hollow reflector having an interior reflective surface, an entrance aperture, and an exit aperture. A light source is positioned adjacent the entrance aperture of the hollow reflector so that some of the light rays produced by the light source pass through the entrance aperture and are reflected by the interior reflective surface of the hollow reflector before passing through the exit aperture.
