  • Patent number: 11796817
    Abstract: An optical arrangement for expanding and uniformizing a beam of light, including a first optical member arranged to receive a collimated incoming light beam, from an incoming beam direction, with a first polarization, the first optical member configured to expand and uniformize the collimated incoming light beam along a first axis to form a first collimated light beam exiting therefrom in a first beam direction; a second optical member adapted to receive the first collimated light beam, from the first beam direction, with the first polarization in relation thereto, the second optical member configured to expand and uniformize the first collimated light beam along a second axis to form a second collimated light beam exiting therefrom in a second beam direction.

  • Publication number: 20220311984
    Abstract: A system for rendering three-dimensional image content for a multi-focal display device. The system includes a first processing sub-system configured to divide the three-dimensional image content into a plurality of virtual depth planes, associate each of the plurality of virtual depth planes with one of a first set of displays and a second set of displays of the multi-focal display device, and generate a first array including the plurality of virtual depth planes. The system also includes a transmission sub-system configured to provide a data channel for transmission of the generated first array. The system further includes a second processing sub-system configured to receive the generated first array and to render the three-dimensional image content in the multi-focal display device based thereon.

  • Publication number: 20220310037
    Abstract: A head-mounted display system for reducing motion-to-photon latency. The head-mounted display system includes a head-mounted display apparatus including a display driver to drive an image on a display, a tracking system to obtain a pose data, a communication interface to form communication between the head-mounted display apparatus and a remote rendering unit, and a display processor configured to collect a first pose data at a first moment of time and a second pose data at a second moment of time and provide the collected pose data to the remote rendering unit, collect a third pose data at a third moment of time, receive a second initial image from a remote rendering unit, use the third pose data to form a second first initial image from the second initial image and receive V-sync signal from the display driver and thereafter provide the second initial image to the display driver.

  • Patent number: 11425343
    Abstract: A display system for presenting three-dimensional images. The display system includes projection unit including projection subassemblies, wherein each projection subassembly includes array of point-like light sources, spatial light modulator and controller; projection screen; and processor. The processor is configured to: process three-dimensional data pertaining to a scene to generate image data of three-dimensional image; and display three-dimensional image, via projection subassemblies of the projection unit, wherein, in each of projection subassemblies, the controller is configured to multiplex operations of individual point-like light sources of the array and the spatial light modulator in a time-sequential manner, based on the image data of three-dimensional image, to display a plurality of segments of three-dimensional image sequentially.

  • Publication number: 20220163816
    Abstract: A display apparatus for presenting three-dimensional imagery, including an optical combiner having a first side, a second side, a third side and a fourth side. The second side is opposite to the first side and the fourth side being is opposite to the third side. Optical combiner further includes a first semi-transparent reflective portion arranged to reflect light incoming from the first side towards the fourth side and a second semi-transparent reflective portion arranged to reflect light incoming from the second side towards the fourth side. Light incoming from the third side passes through the first semi-transparent reflective portion and the second semi-transparent reflective portion towards the fourth side.
