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 38):
An optical system, comprising:\n a light-transmitting substrate having a plurality of surfaces including at least two major surfaces parallel to each other; and an optical device for coupling light waves emanating from a display source into the light-transmitting substrate to effect total internal reflection between the two major surfaces, the optical device including:\n a polarizing beamsplitter deployed non-parallel to the major surfaces of the light-transmitting substrate, \n a retardation plate located next to one of the major surfaces, \n a first reflecting surface located in the light-transmitting substrate, and \n a second reflecting surface located next to the retardation plate, \n wherein the incoming light waves to the optical device include a first component of the light waves in a first polarization state and a second component of the light waves in a second polarization state, and wherein the first component of the light waves are reflected from the polarizing beamsplitter, reflected a first time by the first reflecting surface so as to impinge on the retardation plate, reflected back through the retardation plate by the second reflecting surface to change the polarization state of the first component of the light waves from the first polarization state to the second polarization state, reflected a second time by the first reflecting surface, and transmitted through the polarizing beamsplitter and trapped inside the light-transmitting substrate by total internal reflection.
