Abstract
An image light guide for conveying a virtual image including 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 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, wherein the out-coupling diffractive optic is operable to diffract the image-bearing light beams from the substrate in an angularly decoded form. The in-coupling diffractive optic has three pluralities of periodic diffractive structures symmetric about three equidistant axes and the out-coupling diffractive optic has two pluralities of periodic diffractive structures having a periodicity equivalent to two of the three pluralities of periodic diffractive structures of the in-coupling diffractive optic. The two pluralities of periodic diffractive structures of the out-coupling diffractive optic are also parallel with two of the three pluralities of periodic diffractive structures of the in-coupling diffractive optic.
