Abstract
A compact illumination system for illuminating a scan region on an object may comprise a light source for producing a plurality of light rays. A first reflector is positioned adjacent the light source and is coplanar with a first plane that is located in generally parallel, spaced-apart relation to a scan plane. The first reflector directs toward the scan region some of the light rays produced by the light source. A second reflector is positioned adjacent the light source and is coplanar with a second plane that is not parallel to the scan plane. The second reflector directs toward the scan region some of the light rays produced by the light source.
