    Abstract: An optical device, including a light waves-transmitting substrate has two major surfaces and edges, optical means for coupling light into the substrate by total internal reflection, and a plurality of partially reflecting surfaces (22a, 22b) carried by the substrate. The partially reflecting surfaces (22a, 22b) are parallel to each other and are not parallel to any of the edges of the substrate, one or more of the partially reflecting surfaces (22a, 22b) being an anisotropic surface. The optical device has dual operational modes in see-through configuration. In a first mode, light waves are projected from a display source through the substrate to an eye of a viewer. In a second mode, the display source is shut off and only an external scene is viewable through the substrate.

    Abstract: There is provided an optical system, including a light-transmitting substrate (20) having at least two external major surfaces and edges, an optical element for coupling light waves into the substrate (20) by internal reflection, at least one partially reflecting surface located in the substrate (20), for coupling light waves out of the substrate (20), at least one transparent air gap film (110) including a base (112) and a hyperfine structure (111) defining a relief formation, constructed on the base, wherein the air gap film is attached to one of the major surfaces of the substrate (20), with the relief formation facing the substrate (20) defining an interface plane (58), so that the light waves coupled inside the substrate (20) are substantially totally reflected from the interface plane (58).
