摘要： A head-mounted display (HMD) that includes a high resolution (HR) inset display and a peripheral display. The HR inset display is configured to display an inset region that includes a portion of an image at a first resolution that corresponds to a resolution of a fovea region of a human eye. The peripheral display displays a background region, the background region having a second resolution that is less than the first resolution, the second resolution corresponding to a resolution of a non-fovea region of the human eye. The HMD includes an optics block that combines the inset region and the background region to create composite content at retinal resolution, and direct the composite content to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.

摘要： A head-mounted display (HMD) divides an image into a high resolution (HR) inset portion at a first resolution, a peripheral portion, and a transitional portion. The peripheral portion is downsampled to a second resolution that is less than the first resolution. The transitional portion is blended such that there is a smooth change in resolution that corresponds to a change in resolution between a fovea region and a non-fovea region of a retina. An inset region is generated using the HR inset portion and the blended transitional portion, and a background region is generated using the downsampled peripheral portion. The inset region is provided to a HR inset display, and the background region is provided to a peripheral display. An optics block combines the displayed inset region with the displayed background region to generate composite content.

摘要： A depth camera assembly (DCA) determines depth information for a scene in a field of view of the DCA. The DCA includes a structured light (SL) illuminator, a camera, and a controller. The SL illuminator includes a source assembly, a SL element, a liquid crystal (LC) array, and a polarizer. The source assembly generates light, and the SL element generates a SL pattern using the generated light source. The LC array includes a plurality of addressable cells configured to polarize the SL pattern in accordance with adjustment instructions. The polarizer attenuates portions of the SL pattern based on the polarization of the portions of the SL pattern. The camera captures an image of the SL pattern, and the controller identifies portions of the image that are saturated and generates adjustment instructions based in part on the identified portions of the image, and provides the adjustment instructions to the LC array.

摘要： A virtual scene presented on a display of a virtual reality headset can be adjusted using a varifocal element by changing the shape of one or more optical elements of a pancake lens block, by varying the distance between the two optical elements, or both, based on where in a virtual scene a user is looking. The headset tracks a user's eyes to determine a vergence depth from gaze lines in order to accommodate the user's eye for the determined vergence depth. Accordingly, the shape of one or more optical elements is adjusted, the distance between the two optical elements, or both, is changed to focus light from the display of the virtual reality headset at the vergence depth to keep the user's eye in a zone of comfort as vergence and accommodation change.

摘要： A head mounted display (HMD) includes a field curvature corrected (FC) display to mitigate field curvature in an image that is output to a user's eyes. The FC display includes elements that generate the image light and elements to mitigate field curvature from the image light. The FC display may include a display panel with lenses, a display panel with a reflective polarizer and reflective surface, or other optical elements. The FC display may include a pancake lens configuration including a polarized display with a quarter wave plate, a reflective mirror, and a polarization reflective mirror.
