Abstract
An imaging light guide for conveying a virtual image comprises a first planar waveguide. The first planar waveguide includes first and second co-located in-coupling diffractive optics, each comprising a plurality of periodic diffractive structures, wherein the first in-coupling diffractive optic is operable to diffract a first portion of image-bearing light beams into the first planar waveguide in an angularly encoded form, wherein the first in-coupling diffractive optic is operable to transmit a second portion of image-bearing light beams, a first out-coupling diffractive optic formed along the waveguide, wherein the first out-coupling diffractive optic is operable to expand the first portion of the image-bearing light beams and direct the expanded first portion of image-bearing light beams from the waveguide in an angularly decoded form, and wherein the plurality of diffractive structures of the second in-coupling optic have a periodicity different from the plurality of periodic diffractive structures of the first in-coupling diffractive optic.
