Abstract:
Specific management of configuration of overlap of facets reduces non-uniformity in an image outcoupled toward a nominal point of observation. A waveguide including at least two parallel surfaces, first, middle, and last partially reflecting facets are configured such that in a geometrical projection of the facets onto one of the surfaces the facets overlap, preferably with adjacent facets overlapping and non-adjacent facets starts and ends coinciding along at least a portion of the waveguide.

Claim (Index 1):
An optical device comprising:\n (a) a waveguide having:\n (i) a first of at least one pair of surfaces parallel to each other; \n (ii) a first region at which light is coupled into said waveguide; and \n (iii) a first sequence of facets including:\n (A) a first facet:\n (I) located proximally to said first region; and \n (II) having a first width in a direction between said first pair of surfaces; \n \n (B) a last facet:\n (I) at a distal end of said first sequence of facets from said first region; and \n (II) having a third width in a direction between said first pair of surfaces; and \n \n (C) one or more middle facets:\n (I) between said first facet and said last facet; and \n (II) having a second width in a direction between said first pair of surfaces; \n \n \n (b) wherein each of said facets:\n (i) width is in a plane of said facet; \n (ii) is an at least partially reflecting surface; \n (iii) is at an oblique angle to said first pair of surfaces; \n (iv) has a facet-start on a proximal side of said facet width; and \n (v) has a facet-end on a distal side of said facet width; and \n (c) wherein a geometrical projection is onto one of said first pair of surfaces in a direction of a nominal ray outcoupled from said waveguide, said nominal ray being a central ray of the light being coupled out of said waveguide, (d) said geometrical projection of said last facet and each of said one or more middle facets overlaps a respective said geometrical projection of an adjacent said one or more middle facets and said first facet, and (e) said geometrical projection of said facet-start of said last facet and each of said one or more middle facets coinciding with a respective said geometrical projection of a non-adjacent facet-end of said one or more middle facets and said first facet, (f) said coinciding along at least a portion of said waveguide.
