摘要： A light guide of the tapered-waveguide type includes an input slab (30) for expanding a projected image between an input end and an output end (40); and a tapered output slab (10) arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide (30) is greater in the transverse direction away from the centre line C, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide (10) bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.

摘要： A flat panel lens system as a tapered light guide that has minimal or no margin for fan out. The tapered light guide includes a thin end, and a thick end of which is a bevelled mirror or an optical equivalent. Light is injected into the thin end and the mirror is such that rays injected through a point at the thin end emerge collimated from one of the light guide surfaces, and that collimated rays injected at an appropriate angle through one of the light guide surfaces emerge from a point at the thin end. Bragg gratings can be utilized for color implementations as well. The tapered light guide can be fabricated as a single piece, by extrusion, injection molding, or the combination/variation of extrusion and injection molding, as well as other commonly known techniques.
