TITLE LIGHT GUIDE APPARATUS INVENTOR Lorne A. Whitehead ABSTRACT OF THE DISCLOSURE The light guide apparatus will guide a beam whose rays have a predetermined phase space distribution with a maximum deviation angle .theta.max in a first plane perpendicular to the beam axis. The guiding apparatus includes an optical system positioned at a distance ?/2 from the first plane for receiving light from the edge of the spreading beam along an edge of width ? tan .theta.max and for diverting the light towards thebeam axis to reproduce the predetermined spatial distribution in a second plane perpendicular to the beam axis at a distance ? from the first plane. The optical system can be made from annular or cylindrical, regu- lar or fresnel lenses. A number of systems may be sequentially mounted to guide a beam along any desired distance with in a straight line or perpendicular to its original direction.
