Collimating optical device and system |
摘要 |
There is provided a light-guide, compact collimating optical device, including a light-guide having a light-waves entrance surface, a light-waves exit surface and a plurality of external surfaces, a light-waves reflecting surface carried by the light-guide at one of the external surfaces, two retardation plates carried by light-guides on a portion of the external surfaces, a light-waves polarizing beamsplitter disposed at an angle to one of the light-waves entrance or exit surfaces, and a light-waves collimating component covering a portion of one of the retardation plates. A system including the optical device and a substrate, is also provided. |

1. An optical system, comprising:
an optical device for collimating polarized light waves comprising an arrangement of optical elements, the optical device having at least one light-waves entrance surface and at least one light-waves exit surface; a light-transmitting substrate having at least two major surfaces parallel to each other, edges and a light-waves input aperture; the light-waves input aperture of the light-transmitting substrate being located adjacent to the exit surface of the collimating optical device; an optical element for coupling the collimated light waves into the substrate by internal reflection; at least one partially reflecting surface located in the substrate for coupling the light waves out of the substrate, the partially reflecting surface being non-parallel to the major surfaces of the substrate, and a half-wavelength retardation plate positioned between the input aperture of the light-transmitting substrate and the exit surface of the collimating optical device for rotating polarization of the polarized light waves in the optical system. |
