    Abstract: A system for photographing an object and generating a three-dimensional display of the object without the need for the observer to wear special glasses employs a camera having an electronically tunable liquid crystal lens in which the focal plane of the lens may be adjusted by controlling the voltage on the lens. An operator of the camera focuses the camera on the scene to be imaged and the camera records a series of images at closely spaced focal lengths by varying the voltage applied to the lens between the images. The digitally recorded images are then used to generate a display on a multilayer transparent display substrate with pixel addressing capabilities. Each of the recorded images at the differing focal lengths are displayed on one of the layers of the display screen, with the closest focal length recorded being displayed on the top screen, the one most proximate to the observer, and with successive images on other screens.

  • Patent number: 8087784
    Abstract: Systems and methods for displaying three-dimensional (3D) images are described. In particular, the systems can include a display block made from a transparent material with optical elements three-dimensionally disposed therein. Each optical element becomes luminous when illuminated by a light ray. The systems can also include a computing device configured to generate two-dimensional (2D) images formatted to create 3D images when projected on the display block, by a video projector coupled to the computing device. The video projector is configured to project the 2D images on the block to create the 3D images by causing a set of the passive optical elements to become luminous. Various other systems and methods are described for displaying 3D images.

  • Publication number: 20110317129
    Abstract: A projection autostereoscopic display including an image projector and a stereo screen is provided. The image projector projects an image. The image includes multiple viewing-zone images. The stereo screen receives the image and reflects the image to an observing direction. The stereo screen includes a linear polarizer layer, for receiving and polarizing the image. A first microretarder layer is disposed behind the linear polarizer layer. A second microretarder layer is disposed behind the first microretarder layer by a distance. A reflection-type polarization-reserved diffuser layer is disposed behind the second microretarder layer for reflecting and diffusing the image into various directions while maintaining the polarization state of the image. A switching layer is switched between a transparent state which maintains the polarization state of the image and an opaque state which changes the polarization states of the image to a non-polarization state, to switch between 2D and 3D display modes.

  • Patent number: 8075138
    Abstract: Systems and methods for generating a true 3-D display, where each of a viewer's eyes not only sees a different scene, but the scene changes continuously as the viewer moves his/her head or change his/her position from one angular location to another angular location with respect to the display screen. In one embodiment, a system comprises a set of 2-D image projectors and a display screen. The 2-D image projectors are configured to project individual 2-D images substantially in focus on the display screen. The display screen then diffuses (or reflects) each pixel from each of the 2-D images into a small angular slice. This enables the viewer observing the display screen to see a different one of the 2-D images with each eye. Further, the image seen by each eye varies as the viewer moves his or her head with respect to the display screen.

  • Patent number: 8023185
    Abstract: A transmission type screen for stereoscopic images having a transmission layer includes an incident surface having a gloss surface, a transmission layer having a refractive index less than 1.55, a transmissivity more than 60%, and an imaging surface having surface particle sizes of 40 to 400 mesh that avoids a hot spot. The imaging surface is formed on the final surface through which images are transmitted, so that the components operate in an organic fashion with respect to each other. The polarization degree of stereoscopic images is maximized thereby increasing the three-dimensional effect and the transmissivity, and enables viewers to view images clearly several times better than with a conventional screen.

  • Patent number: 7993016
    Abstract: Aspects of the present invention involve novel display screens comprising light diffusion and retro-reflectivity. In embodiments, a retro-reflective light diffusion screen can be used to generate a three-dimensional autostereoscopic display by generating a plurality of viewing windows wherein each viewing window depicts a unique perspective image view. In embodiments, the retro-reflective light diffusion screen comprises a transparent medium layer between the retro-reflector surface and the light diffuser layer to help reduce ghost images. In embodiments, the retro-reflective light diffusion screen comprises a lenticular layer positioned such that the light diffuser layer is between the lenticular layer and the retro-reflective surface and is also positioned so that the light diffuser layer is at a focal plane of the lenticular layer.

  • Patent number: 7959294
    Abstract: An apparatus and an associated method for displaying 3D images includes a screen and a screen illuminating system. The screen has diffusion characteristics for direction selectively forwarding light. The screen illuminating system includes modules for generating light beams incident on points of the screen. The apparatus is configured to impart an exit divergence to the exiting light beams being transmitted through or reflected from the screen. Each module provides one beam in one direction with a convergent section. The beams are focused on the screen where the convergence (?c) of an incident light beam is not greater than the exit divergence (?x) of an exiting light beam.

    Abstract: A vision system that forms a map of a scene proximate a platform, e.g., a vehicle, that determines the actual ground plane form the map, and that corrects the map for differences between the actual ground plane and an assumed ground plane. The vision system may remove the actual ground plane from the map to prevent false positives. The vision system can further identify and classify objects and, if appropriate, take evasive action.

    Abstract: An autostereoscopic 3-D image is provided in a viewing zone without the need for 3-D glasses by use of one or more projectors that project two or more images having projected exit pupils separated horizontally by no more than an average human interocular spacing onto a 3-D forming screen (which is a lenticular or a raster barrier screen) with a substantially smooth and nominally white back projection surface and a front side with multiple individual vertical elements that project left and right images so that the 3-D forming screen retro-reflects projected light on the screen received from a light source back to the light source.
