Abstract
A display includes a first reflecting surface, a second reflecting surface, and a beam splitter. The second reflecting surface is positioned parallel with respect to the first reflecting surface, and the beam splitter is disposed between the first and second reflecting surfaces. The beam splitter includes a first transmissive substrate having opposed first and second sides and a length extending from a first end to a second end. A first layer of material is disposed on at least one of the first or second sides of the first transmissive substrate. The first layer of reflective material extends from the first end of the first transmissive substrate to a location along the length of the first transmissive substrate.
