    摘要： An image light guide for conveying image bearing light comprising a substrate operable to propagate image-bearing light beams along a length thereof. An in-coupling diffractive optic is formed along the substrate and is operable to diffract a portion of image-bearing light beams from an image source into the substrate in an angularly encoded form. An out- coupling diffractive optic is formed along the substrate at least partially in a plane having an x-axis and a y-axis, and is operable to diffract a portion of the image-bearing light beams from the substrate in an angularly decoded form. The out-coupling diffractive optic comprises a first plurality of periodic structures and a second plurality of periodic structures operable to diffract a portion of the image-bearing light beams into diffractive orders. The first and second pluralities of periodic structures comprise a plurality of vertices, wherein each adjacent vertex along the x-axis is offset in the y-axis direction.

    摘要： An image light guide for conveying a virtual image, including a waveguide, an in-coupling diffractive optic operable to direct image-bearing light beams into the waveguide, and an out-coupling diffractive optic operable to direct the image-bearing light beams from the waveguide toward an eyebox. The out-coupling diffractive optic having two or more zones each including a set of diffractive features, wherein successive zones along one dimension of the out-coupling diffractive optic have different respective sets of diffractive features, wherein the diffractive features are operable to direct image-bearing light beams of a first pixel incident upon the diffractive features at a first angle whereby the directed image-bearing light beams of the first pixel further propagate within the waveguide, and wherein the diffractive features are operable to out-couple a portion of the image-bearing light beams of the first pixel incident upon the diffractive features at a second angle.
