Abstract
An optical device includes input and output apertures (), a light-transmitting substrate (), a coupling-in element () positioned outside of the substrate for coupling light waves having a field-of view into the substrate, a first flat reflecting surface () located between two major surfaces () of the light-transmitting substrate for total internal reflection of the coupled-in light waves from the major surfaces, and a second flat reflecting surface () located between the two major substrate surfaces for coupling light waves out of the substrate for redirecting into a viewer's eye by an optical element (). The substrate and coupling-in element () are formed of substantially different optical materials and the ratio between the fields of view of the light waves coupled-out from the substrate into the viewers' eye and of the light waves coupled inside the substrate, is substantially bigger than the refractive index of the substrate.
