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 20):
An optical system, comprising:\n a light-transmitting substrate having a plurality of surfaces including at least two major external surfaces parallel to each other; at least one partially reflecting surface located in the light-transmitting substrate for coupling light waves out of the light-transmitting substrate; 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 external surfaces, the optical device including a polarizing beamsplitter and a retardation plate, wherein light waves from the display source pass at least once through the retardation plate prior to being coupled into the light-transmitting substrate, and wherein the polarizing beamsplitter is oriented so that the coupled-in light waves are reflected from the beamsplitter at oblique angles with respect to the major external surfaces, such that the reflected light waves are trapped inside the light-transmitting substrate by total internal reflection and are reflected at least once by one of the major external surfaces before being coupled out of the light-transmitting substrate by the partially reflecting surface.
