Illumination system for illuminating a scan region on an object
First Claim
1. An illumination system for illuminating a scan region on an object, comprising:
- a hollow reflector having an interior reflective surface and an exit aperture;
a light source positioned within said hollow reflector, said light source producing a plurality of light rays, some of the light rays produced by said light source being reflected by the interior reflective surface of said hollow reflector before passing through the exit aperture;
a first reflector positioned adjacent a first side of the exit aperture of said hollow reflector; and
a second reflector positioned adjacent a second side of the exit aperture of said hollow reflector, said first and second reflectors being positioned in non-parallel, spaced-apart relation to one another, said first and second reflectors at least partially collimating light passing through the exit aperture of said hollow reflector to form a collimated beam.

Abstract
An illumination system for illuminating a scan region on an object may comprise a hollow reflector having an interior reflective surface and an exit aperture. A light source positioned within the hollow reflector produces a plurality of light rays, some of which are reflected by the interior reflective surface of the hollow reflector before passing through the exit aperture. First and second reflectors positioned adjacent respective first and second sides of the exit aperture of the hollow reflector at least partially collimate light passing through the exit aperture of the hollow reflector to form a collimated beam.

10. An illumination system for illuminating a scan region on an object, comprising:
-
a body having an interior wall defining a generally cylindrically shaped interior reflective surface, the interior wall of said body also defining a generally elongate axial opening therein located at a first radial position on the interior wall of said body;
a light source positioned within the generally cylindrically shaped interior reflective surface defined by said body;
a first reflector positioned adjacent a first side of the elongate axial opening defined by the interior wall of said body; and
a second reflector positioned adjacent a second side of the elongate axial opening defined by the interior wall of said body, said first and second reflectors being positioned in non-parallel, spaced-apart relation to one another, said first and second reflectors at least partially collimating light passing through the exit aperture of said hollow reflector to form a collimated beam. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An illumination system for illuminating a scan region on an object, comprising:
-
hollow reflector means for defining an interior reflecting surface and an exit aperture;
light source means positioned within said hollow reflector means for producing a plurality of light rays; and
collimating reflector means positioned adjacent the exit aperture defined by said hollow reflector means for at least partially collimating light exiting the exit aperture defined by said hollow reflector means to form a collimated beam. - View Dependent Claims (19)

20. A method for illuminating a scan region on an object, comprising:
-
providing a hollow reflector having an interior reflecting surface and an exit aperture;
providing a collimating reflector adjacent the exit aperture of the hollow reflector; and
directing a plurality of light rays onto the interior reflecting surface of the hollow reflector, the interior reflecting surface reflecting some of the light rays through the exit aperture in the hollow reflector, the collimating reflector at least partially collimating light exiting the exit aperture in the hollow reflector to form a collimated beam.
