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 20):
The device of  claim 1  wherein a first angle of said partially reflecting facets in a first set of said at least two sets of facets is selected from the group consisting of:\n (a) different from a second angle of said partially reflecting facets in a second set of said at least two sets of facets, said angles being relative to said first pair of external surfaces, and \n (b) substantially the same as a second angle of said partially reflecting facets in a second set of said at least two sets of facets, said angle being relative to said first pair of external surfaces and said first set is rotated relative to said second set.
