摘要： This document describes various apparatuses embodying, and techniques for implementing, a virtual image device. The virtual image device includes a projector and a lens configured to generate a virtual image as well as two diffraction gratings, substantially orthogonally-oriented to each other, that act to increase a field-of-view of the virtual image. The virtual image device can be implemented as a pair of eyeglasses and controlled to generate the virtual image in front of lenses of the eyeglasses so that a wearer of the eyeglasses, looking through the lenses of the eyeglasses, sees the virtual image.

摘要： A light guide device can provide a backlight for an LCD or a projection display. The light guide device includes a light-input end and an opposing end, opposing left and right sides which join the light-input end and the opposing end, and opposing front and back surfaces which join the light-input end and the opposing end. A birefringent film is provided on the opposing left and right sides of the light guide which switches a polarization of incident light. Incident light is provided at the light-input end having a right-handed circular polarization, in addition to light having a left-handed circular polarization. Light emitted from the front surface passes through a linear polarizer which selectively passes light to allow privacy of viewing by a user. The incident light can be provided at the light-input end using one or more cuboid rods, slab light guides, or discrete light sources.

摘要： A wide field-of-view virtual image projector includes a rod light guide that is embossed with at least a first diffraction grating and a second diffraction grating that is substantially parallel to the first diffraction grating. The first diffraction grating is configured to receive a first light ray, and to project first diffracted light rays from the rod light guide at a first range of angles. The second diffraction grating is configured to receive a second light ray, and to project second diffracted light rays from the rod light guide at a second range of angles. The virtual image projector further includes a slab light guide configured to receive the first diffracted light rays and the second diffracted light rays, and to diffract the first diffracted light rays and the second diffracted light rays out of the slab light guide to generate a virtual image with a wide field-of view.
