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: A method is described for fabricating an optical device that includes a light waves-transmitting substrate having at least two major surfaces and edges and a plurality of partially reflecting surfaces carried by the substrate, wherein the partially reflecting surfaces are parallel to each other and not parallel to any of the edges of the substrate. The method includes providing at least one transparent flat plate and plates having partially reflecting surfaces and optically attaching together the flat plates so as to create a stacked, staggered form. From the stacked, staggered form, at least one segment is sliced off by cutting across several plates and the segment is ground and polished to produce the light waves-transmitting substrate. The plates are optically attached to each other by an optically adhesive-free process.
