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.

摘要： A hexahedral polarization beamsplitter is constructed with four substantially triangular prisms with a polarizing beamsplitter located within each of the interfaces between the assembled prisms. An input side of the assembly receives an unpolarized beam and two opposing output sides of the assembly transmit orthogonally polarized portions of the unpolarized beam in opposite directions. The polarizing beamsplitters are arranged at the interfaces so that each of the orthogonally polarized portions of the unpolarized beam is both reflected by one of the polarizing beamsplitters and transmitted by another of the polarizing beamsplitters.

摘要： An imaging apparatus has a projector apparatus that projects light for forming a first image and a second image. A first pupil expander lies in the path of projected light and is configured to direct light to a viewer to form a first virtual image at infinity focus. A second pupil expander lies in the path of the projected light and is configured to direct light through a first lens and to the viewer to form a second virtual image near a focal plane of the first lens. A second lens is disposed to condition light from a visual scene lying beyond the second pupil expander.

摘要： A head-mounted imaging apparatus includes a frame that houses a left-eye and a right-eye imaging apparatus. Each imaging apparatus forms a virtual image to an eye of an observer and includes a projector, a planar waveguide, and an optical coupler. The projector is supported by a temple member of the frame and emits a central projected light beam along a projection axis. The planar waveguide accepts the projected light beam through an input aperture and forms an expanded light beam that is output from an output aperture and directed toward the observer's eye. The optical coupler receives the central projected light beam along a first axis that is at an obtuse angle with respect to the waveguide surface, and the optical coupler redirects the central projected light beam along a second axis that is at an acute angle with respect to the waveguide surface.

摘要： A near-eye display includes an image generator that generates angularly related beams over a range of angles for forming a virtual image and a waveguide that propagates the angularly related beams over a limited range of angles. An input aperture of the waveguide includes a plurality of controllable components that are selectively operable as diffractive optics for injecting subsets of the angularly related beams into the waveguide. An output aperture of the waveguide includes a plurality of controllable components that selectively operable as diffractive optics for ejecting corresponding subsets of the angularly related beams out of the waveguide toward an eyebox. A controller synchronizes operation of the controllable components of the output aperture with the propagation of different subsets of angularly related beams along the waveguide for ejecting the subsets of angularly related beams out of the waveguide for presenting the virtual image within the eyebox.

摘要： A compact near eye display generates image segments for a first dimension of an intended image. Each of the image segments is transformed into angularly distinguished beamlets that converge through a first dimension pupil within an eyebox. A scanning optic angularly separates the angularly distinguished beamlets of different image segments for creating a second dimension pupil. The angularly distinguished and separated beamlets propagate along a waveguide in a form that minimizes the thickness of the display in front of a viewer's eye and limits the overall size of the optics required to support the projection of virtual images into the viewer's eye.

摘要： A near-eye display projects virtual images from an image generator to an eyebox within which the virtual images can be seen by a viewer. A first optical path conveys image-bearing light from the image generator to a selectively reflective powered optic and a second optical path conveys the image-bearing light along a line of sight from the selectively reflective powered optic to the eyebox. First and second selectively reflective surfaces fold the first optical path with respect to the second optical path to locate the image generator out of the line of sight to the eyebox. The image generator is effectively inclined to the line of sight to the eyebox for reducing a thickness of the near-eye display. The selectively reflective powered optic is oriented normal to local overlapping portions of the first and second optical paths at the selectively reflective powered optic.
