Abstract: There is provided an optical device, including an input aperture, an output aperture, at least first and second light-transmitting substrates each having two major surfaces and edges, an input surface for coupling light waves into the substrate for effecting total internal reflection inside the substrate, and an output surface for coupling light waves out of the substrate, a major surface of the first substrate is attached to a major surface of the second substrate and the input surface of the first substrate is a partially reflecting surface, such that part of the light waves passing through the input aperture is partially reflected by the partially reflecting input surface and coupled into the first substrate and another part passes through the partially reflecting input surface and is coupled by the input surface of the second substrate into the second substrate.

Abstract: There is provided an optical device, including a light-transmitting substrate having at least two major surfaces and edges, an optical element for coupling light waves into the substrate to effect total internal reflection, and at least one flat reflecting surface having at least one active side located between the two major surfaces of the light-transmitting substrate for coupling light waves out of the substrate, characterized in that light waves trapped inside the substrate are reflected at least twice by the active side of the reflecting surface before being coupled out from the substrate.
