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: An optical system includes a light-transmitting substrate having at least two external major surfaces and edges and an optical element for coupling light waves into the substrate, by total internal reflection. At least one partially reflecting surface is located in the substrate for coupling light waves out of the substrate, and at least one transparent layer, having a refractive index substantially lower than the refractive index of the light transmitting substrate is optically attached to at least one of the major surfaces of the substrate, defining an interface plane. The light waves coupled inside the substrate are substantially totally reflected from the interface plane between the major surface of the substrate and the transparent layer.
