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 50):
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 module for collimating light waves emanating from a display source, the optical module including:\n a folding prism including a first polarizing beamsplitter and a second polarizing beamsplitter, and having a plurality of surfaces including at least two major surfaces parallel to each other, \n a first retardation plate located next to one of the major surfaces of the prism, and \n a first lens and a second lens, each located next to the first retardation plate; and \n an optical device for coupling the collimated light waves from the optical module into the light-transmitting substrate to effect total internal reflection between the two major surfaces, the optical device including:\n a third polarizing beamsplitter, \n a second retardation plate located next to one of the major surfaces of the light-transmitting substrate, and \n a reflecting surface located next to the second retardation plate, \n wherein light waves from the display source pass at least once through the first polarizing beamsplitter, are reflected at least once from a reflecting surface of the first lens, reflected at least once from the first polarizing beamsplitter, reflected at least once from a first of the major surfaces of the prism, reflected at least once by the second polarizing beamsplitter, reflected at least once from a reflecting surface of the second lens, pass at least four times through the first retardation plate, pass at least once through the second polarizing beamsplitter, pass at least twice through a second of the major surfaces of the prism, pass at least once through the second polarizing beamsplitter, reflected at least once from the reflecting surface located next to the second retardation plate, pass at least twice through the second retardation plate, and reflected at least once from the second polarizing beamsplitter prior to being coupled in to the light-transmitting substrate.
