Abstract: According to one implementation, an image generation system includes a rotor, a base including a motor for spinning the rotor about an axis of rotation, a display secured to the rotor, the display including a display surface, and a blur screen secured to the display. The blur screen has a vertical edge substantially parallel to the axis of rotation and includes a first light emission barrier, a second light emission barrier, and a horizontal gap having a width substantially perpendicular to the vertical edge separating the first light emission barrier from the second light emission barrier. The first light emission barrier and the second light emission barrier are configured to substantially prevent rotational blur of an image displayed by the display surface while the display and the blur screen are spun by the motor and the rotor.

Abstract: A transparent display system is provided where broadcast talent (or presenter) can see interactive content, tool palettes, prompts (and the like) as well as their own sketches and annotations, but a viewing audience sees only the broadcast talent and content intended for the viewing audience with the talent's annotation thereof. A transparent scattering screen together with optical filtering or gating of a first optical property of the light (e.g., polarization-based or wavelength-based) is used such that the first property of the light is projected onto the screen so the talent can see the projection, and a camera-side filter blocks the first property of the light so it is not seen by the camera. Simultaneously, a broadcast talent (or presenter) is illuminated by light having properties other than the first property, which allows the talent image to pass through the screen and the camera-side filter allowing the talent to be seen by camera.

Abstract: A holographic display system for generating a super hologram with full parallax in different fields of view in the horizontal and vertical directions. The system includes an array of holographic display devices, e.g., spatial light modulators (SLMs), operable to provide a plurality of holographic images of a scene from differing viewpoints of the scene. Each SLM is operated concurrently to output a narrow field of view, elemental hologram. The system includes coarse integral optics combining the holographic images into a single hologram (“super hologram”) viewable in a hologram image plane a distance from the course integral optics. The coarse integral optics combine the holographic images by providing angular tiling of the holographic images, e.g., bending the axes of parallel lenses. In this manner, the field of view, in one direction, of the super hologram is based on the number of holographic display devices provided in the array in one direction.

Abstract: An autostereoscopic apparatus for providing a 3D image to a viewer at a range of vertical eye locations. The apparatus includes a projection screen with a light receiving surface that is horizontally retroreflective and vertically diffusive. The apparatus includes a projector assembly including at least two projectors arranged side-by-side such that projection lenses of the projectors are horizontally aligned in a row. The apparatus includes a controller selectively operating the projectors to project at least two differing point-of-view images. The projection screen may take a number of useful embodiments to implement the autostereoscopic apparatus. For example, the projection screen may include a bottom layer including a retroreflective film that is retroreflective at least in the horizontal direction such as a brightness enhancement film and a top layer formed of a transparent sheet of lenticular material arranged for vertical diffusing.

Abstract: A multi-planar plenoptic display assembly with multiple spatially-varying light emitting and modulating planes. The display assembly includes at least one light emitting device and may include a modulating device used in conjunction according to display methods taught herein to display light field data. A display assembly controller may be used to render a light field with depth into a multi-planar plenoptic display assembly by assigning decomposed portions of the light field to the display assembly for display or presentation by differing ones of the emitting elements and by operating a modulating device to provide a parallax barrier. In one embodiment, a projector is used with bi-state screens. In another embodiment, two automultiscopic displays (either parallax barrier or lenticular lenses) are overlaid with a beam splitter. In a further embodiment, an oscillating mirror is used to temporally and optically move one automultiscopic layer (either parallax barrier or lenses) through space.

Abstract: A method for performing light-based calibration of optics with caustic surfaces. The method includes mapping a light detecting device to a programmable light source. Then, the method includes operating a calibration light source to direct light onto one or more caustic surfaces of an optical assembly, e.g., an assembly of one or more lenses, facets, lenticules, and lenslets. The method may then involve, with the light detecting device, capturing an image of a projection surface of the optical assembly, which is opposite the one or more caustic surfaces in the optical assembly, as the projection surface is illuminated by the light from the light source. Further, the method includes processing the captured image, along with the mapping of the light detecting device to the programmable light source, to generate a calibration map of the optical assembly including the caustic surfaces.

Abstract: A method for providing a three dimensional (3D) drawing experience. The method includes capturing a 3D image of a participant and then processing this image to key the participant's image from a background. The keyed participant's image is mixed with a 3D background image such as frames or scenes from a 3D movie, and the mixed 3D image is projected on a projection screen. For example, left and right eye images may be projected from a pair of projectors with polarization films over the lenses, and the projection screen may be a polarization-maintaining surface such as a silver screen. The user moves a drawing instrument in space in front of the projection screen, and spatial tracking performed to generate a locus of 3D positions. These 3D positions are used to create a 3D drawing image that is projected with the 3D background and participant images in real time.

Abstract: A three dimensional (3D) display apparatus for without 3D glasses. The display apparatus includes a display element operated to display left and right eye images. A back light assembly back lights the display element and includes light bars with a row of infrared (IR) light receivers that are each paired to a white light emitting diode (LED). Viewers in seats in tiered rows such that their heads are in known viewing locations. Left and right side illuminators illuminate the left and right sides of the faces of the viewers with IR light. The IR light is synchronized with display of the left and right eye images. IR reflected from viewers' faces pass through the display element and is focused onto IR light receivers, which causes LEDs to emit light onto the display element and provide left or right eye images to the viewers at their left or right eyes.

Abstract: A transparent display with a dynamic mask for generating three dimensional (3D) imagery. The display or apparatus includes a display element that is transmissive and that is selectively operable to display an image on the display element. The apparatus includes a dynamic mask element that is transmissive to light and that is positioned adjacent to the display element. The dynamic mask element is selectively operable to provide a mask with a shape and a size corresponding to the displayed image. The mask is positioned on the dynamic mask element so as to be adjacent to the first location, e.g., to be behind the displayed image, and, typically, the mask includes portions that are semi-transparent or opaque to block light from passing from the background through the displayed image and from passing through the display element at the location of the displayed image into the background to avoid double imaging.
