摘要： Unwanted reflections in a polarization diversity based optical beam scanner of a projector display may be reduced by mounting a quarter-wave plate optically in contact with the scanning mirror. This lowers the amplitude of the reflection from a rear surface of the quarter-wave plate. A residual reflection from the quarter-wave plate to mirror interface will be scanned with the main scanned light beam, reducing brightness and noticeability of image artifacts caused by undesired or spurious reflections in the optical beam scanner.

摘要： Various embodiments set forth high-resolution liquid crystal displays and components thereof. In some embodiments, light emitted by a high-resolution green color liquid crystal display is combined, via a combiner, with light emitted by at least one lower-resolution red and blue color liquid crystal display. The red and blue color display(s) may include a single display or two displays positioned on opposing sides of the combiner. The combiner may be a dichroic or polarization-based combiner. Combined light from the green color display and the red and blue color display(s) is passed through collimating optics, such as a pancake lens or a Fresnel lens, toward a viewer's eye.

摘要： A display device includes a projector and a display that has a first surface and a second surface. The projector is configured to project image light toward the display. The display is configured to output diffused image light from the first surface and to transmit ambient light from the second surface to the first surface. The display device also includes an optical assembly that has a substrate with substantially uniform thickness. The optical assembly is configured to receive the diffused image light and transmit a portion of the diffused image light output from the first surface of the display at a first optical power. The optical assembly is also configured to receive the ambient light and transmit a portion of the ambient light through the optical assembly at a second optical power that is less than the first optical power.

摘要： An optical device for providing illumination light includes an optical waveguide and a plurality of polarization selective elements. The plurality of polarization selective elements is disposed adjacent to the optical waveguide so that a respective polarization selective element receives light in a first direction, and redirects a first portion of the light in a second direction. A second portion, distinct from the first portion, of the light undergoes total internal reflection, thereby continuing to propagate inside the optical waveguide.

摘要： An optical device includes a spatial light modulator and an optical waveguide with a plurality of extraction features. The plurality of extraction features is positioned relative to the optical waveguide so that a respective extraction feature receives light, having propagated within the optical waveguide, in a first direction and directs a first portion of the light in a second direction distinct from the first direction to exit the optical waveguide and illuminate at least a portion of the spatial light modulator. The plurality of extraction features is also positioned relative to the optical waveguide so that a respective extraction feature directs a second portion, distinct from the first portion, of the light to undergo total internal reflection, thereby continuing to propagate within the optical waveguide.

摘要： A display device includes a frame, a display, an optical assembly, and a display-moving assembly connected to the display and the frame. The display-moving assembly is configured to move the display between multiple different positions, including a first position and a second position. When the display is in the first position, the display is configured to output image light in a first direction. The first direction is substantially parallel to an optical axis of the optical assembly. When the display is in the second position, the display is positioned away from the optical axis of the optical assembly.

摘要： The disclosure describes artificial reality (AR) systems and techniques that enable a change in focus of virtual image content without substantially changing magnification of real-world content. For example, an AR system includes a virtual image content output device, a first tunable lens on a real-world side of the virtual image content output device, a second tunable lens on an eye side of the virtual image content output device, and at least one compensating lens. The at least one compensating lens is configured to substantially eliminate magnification changes of real-world light between a real-world end of the optical system and an eye-side end of the optical system as a focal power of at least one of the first tunable lens or the second tunable lens changes.

摘要： A head-mounted display device for providing augmented reality contents to a wearer includes a light projector and a pancake combiner. The light projector is configured to project a light having a first polarization for rendering images based at least on the augmented reality contents. The pancake combiner is configured to combine the light from the light projector and light from an outside of the head-mounted display device for providing an overlap of the rendered image and a real image that corresponds to the light from the outside of the head-mounted display device. The pancake combiner is also configured to direct the light from the light projector toward a pupil of an eye the wearer.
