摘要： An imaging apparatus includes an in-coupling diffractive optic directs image-bearing light beams into a planar waveguide, an out-coupling diffractive optic directs the image-bearing light beams from the waveguide toward a viewer eyebox, and a turning diffractive optic directs the image-bearing light beams along the waveguide between the in-coupling and out-coupling diffractive optics. The grating vectors of the in-coupling and out-coupling diffractive optics differ in magnitude and orientation while the grating vectors of all three diffractive optics sum to substantially zero. The turning diffractive optic is further arranged to preserve a desired angular relationship of the propagating image bearing beams within the waveguide.

摘要： An imaging apparatus for conveying a virtual image including a waveguide having first and second surfaces. An in-coupling diffractive optic and an out-coupling diffractive optic arranged along one of the first and second surfaces, wherein the in-coupling diffractive optic is operable to direct image-bearing light beams into the waveguide for propagation by total internal reflection, and wherein the out-coupling diffractive optic is operable to direct at least a portion of the image-bearing light beams from the waveguide through the second surface toward an eyebox. An at least partially transparent outer cover located adjacent to the first surface, and a circular polarizer arranged between the waveguide and the outer cover, wherein the circular polarizer is operable to circularly polarize at least a portion of image-bearing light beams transmitted through the first surface and to prevent at least a portion of image-bearing light beams transmitted through the first surface from reentering the waveguide as a result of reflection from the outer cover.

摘要： 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.

摘要： A near-eye display system that employs a volume holographic element containing distinct but overlapped planar volume gratings, each corresponding to a subset of pixels in the display. The volume gratings are illuminated using light incident from angles, and at wavelengths, that match the conical diffraction conditions for each grating, thereby achieving both high diffraction efficiency and a wide field of view. A single volume grating can thus be used to display thousands of pixels independently with high efficiency.

摘要： An imaging apparatus for forming dual virtual images includes a planar waveguide, an in-coupling diffractive optic that directs a set of image-bearing light beams into the waveguide, and an out-coupling diffractive optic that directs the set of image-bearing light beams from the waveguide toward a viewer eyebox. The out-coupling diffractive optic includes an array of contiguous diffractive zones, each of which has a set of diffractive features having at least one of a common orientation and a common pitch. A succession of the zones along one dimension of the array have respective sets of diffractive features that progressively vary in at least one of orientation and pitch in a stepwise manner. The out-coupling diffractive optic is arranged together with the array of contiguous diffractive zones for forming a virtual image that is viewable from the eyebox at a near focus distance.
