Abstract:
There is provided an optical system, including a light-transmitting substrate having at least two major surfaces parallel to each other edges, and an optical device for coupling light into the substrate by total internal reflection. The device includes a polarization sensitive reflecting surface.

Claim (Index 1):
An optical system, comprising:\n a light-transmitting substrate having a plurality of surfaces including at least two major surfaces parallel to each other; an optical device for coupling light waves emanating from a display source into the light-transmitting substrate by total internal reflection, the optical device including a polarizing beamsplitter deployed non-parallel to the major surfaces of the light-transmitting substrate; a retardation plate located next to one of the major surfaces; and a lens located next to the retardation plate, wherein the incoming light waves to the optical device are p-polarized or s-polarized and transmitted through the polarizing beamsplitter so as to impinge on the retardation plate which converts the light waves into circular polarized light, and wherein the transmitted light waves are subsequently reflected back through the retardation plate by a reflecting surface of the lens so as to change the polarization state of the light waves such that the light waves are s-polarized or p-polarized, respectively, and wherein the s-polarized or p-polarized light waves are reflected from the polarizing beamsplitter and trapped inside the light-transmitting substrate by total internal reflection.
