Abstract:
An optical device includes a lightguide having a first pair of external surfaces parallel to each other, and at least two sets of facets. Each of the sets including a plurality of partially reflecting facets parallel to each other, and between the first pair of external surfaces. In each of the sets of facets, the respective facets are at an oblique angle relative to the first pair of external surfaces, and at a non-parallel angle relative to another of the sets of facets. The optical device is particularly suited for optical aperture expansion.

Claim (Index 15):
The device of  claim 11  wherein said lightguide includes:\n (a) a first section of said section of facets having a first boundary pair of surfaces, and \n (b) a second section of said section of facets having a second boundary pair of surfaces, \n (c) wherein said first and second boundary pairs of surfaces are parallel; and \n (d) at least one interface, each said interface:\n (i) being at least partially between two sections, and \n (ii) parallel to said first pair of external surfaces, \n \n (e) wherein said interface is at least one selected from the group consisting of:\n (i) a partially reflecting surface, \n (ii) a partially reflective optical coating, \n (iii) a transition from a material of one of said sections to another material of another of said sections, \n (iv) a polarization modifying coating, and \n (v) a flexible intermediate layer.
