Abstract: An apparatus for generating light-based special effects viewable in daylight. The apparatus includes a barrel with opaque sidewalls defining an interior space accessible via a muzzle. The apparatus includes a light element positionable within the interior space and further includes a light positioning assembly. The apparatus includes a trigger element operable to receive user input to initiate operations of the light element and the light positioning assembly. A controller is provided that responds to the user input to operate the light positioning assembly to first move the light element out of the interior space through the muzzle and to second retract the light element back into the interior space. The controller concurrently operates the light element to generate the light when the light element is moved out of the interior space and to terminate the generating of the light when the light element is retracted back into the interior space.

Abstract: A display system is provided that combines the use of a display element with a beamsplitter and at least one retroreflector to provide an image (2D or 3D depending upon the output image from the display element) that appears to be floating in space some distance from the beamsplitter. For example, light that is bounced off/reflected and/or that is transmitted through the beamsplitter may be reflected from the reflective surface of the retroreflector toward the beamsplitter. The beamsplitter directs this light, through reflection or transmission, into a viewing space such that the 2D or 3D image can be viewed by a viewer as it appears to float a distance from the nearest surface of the beamsplitter and, typically, some distance above the ground/floor upon which viewers are walking. The floating image may be relatively bright so that it is viewable in low and brighter light conditions.

Abstract: A special effects apparatus for generating an illusion of a moving beam of light in midair. The apparatus includes a light source, such as a laser light source outputting colored light, generating a beam of light that is aimed along a linear light travel path. The apparatus further includes a dynamic light receiving assembly, and this assembly includes: an elongated support rod; a light receiving element attached to a first end of the support rod; and a driver coupled to a second end of the support rod opposite the first end of the support rod. The driver rotates the support rod about the second end at a high rotation rate, and the light receiving element moves along an arcuate travel path that intersects the linear light travel path of the beam of light. The arcuate travel path of the light receiving element and the linear light travel path are coplanar.

Abstract: A method for creating a volumetric display. The method includes projecting a first light type onto a planar projection surface to display first content and, concurrently with projection of the first light type, first projecting a second light type onto the planar projection surface to display second content that at least partially overlays the displayed first content. The method includes second projecting the second light type onto a three dimensional (3D) set of reflective elements, whereby the second content moves between the planar projection surface and the 3D set. The first light type may be non-coherent light and the second light type may be laser light (or coherent light). While projected on the planar projection surface, the coherent light is at a first illumination level that matches or is somewhat greater than the non-coherent light, and a second much higher illumination level is used when projecting onto the 3D set.

The system includes a display device with a monitor having a screen operable to output light associated with still or animated images. The system further includes an optical block comprising a plurality of optical fibers bonded together to define parallel guide paths. First ends of the optical fibers define a first block surface and second ends of the optical fibers define a second block surface. The first block surface is positioned adjacent the screen to receive and transmit the output light along the guide paths to the second block surface. The system includes a textured display element covering the second block surface for receiving light exiting the second block surface and having a non-planar exterior surface emitting or projecting the received light. The textured display element has a body with an optical index matching that of the optical fibers.

Abstract: A display system that is adapted to provide control blow-by. The display system includes a projector that is operable to project light through a lens. The system also includes a first polarizer positioned proximate to the lens receiving and first polarizing the projected light. The display system further includes a projection screen assembly that includes a transparent projection screen and a second polarizer. The projected light first strikes the transparent projection screen causing a projected image to be displayed. The second polarizer is adapted to second polarize the projected light to provide cross-polarization and reduce blow-by in the display system. The first and second polarizers are configured with first and second axes of polarization, and the first and second polarizers are arranged in the display system with the first axis of polarization substantially orthogonal to the second axis of polarization to provide full cross-polarization of the projected light.

Abstract: An apparatus providing a viewer with a blend of displayed and reflected content. The apparatus includes an emissive display device with a display screen operable providing digital content. The emissive display device includes a light source selectively articulating and transmitting light through the display screen at a particular illumination level to display digital content such as text and graphics. The apparatus includes a thematic overlay positioned over the display screen with a front surface configured to provide diffuse reflection of light striking the front surface from a viewer space such that the front surface appears substantially opaque to the viewer and the viewer cannot see the display screen when the light source is inactive or at low brightness. When the light source is in active mode, the displayed content is visible as emissive display content concurrently with the diffuse reflection content but the display screen remains hidden from view.

Abstract: A projector for projecting diffracted light in a selectable pattern and/or animation on a display surface. The apparatus includes a light source providing one or more beams of coherent light from one or more lasers. The apparatus includes a diffraction assembly in the path of the light source to generate diffracted light by diffracting the laser light with one, two, or more diffraction grating patterns and, optionally, with a diffraction glass or other material. An active mask is provided with a raster that receives the diffracted light and that includes a plurality of optical shutter elements that are selectively operable to project a portion of the diffracted light from the active mask toward the display surface. In one example, the active mask includes a liquid crystal display panel to provide a grid of addressable programmable pixels that are turned on and off to project portions of the diffracted light.

Abstract: A three-dimensional (3D) display device combining two-dimensional (2D) images from two image sources to create a 3D image. The 3D display device utilizes a beam combining film that includes a prismatic front surface and a planar back surface. The film transmits light striking its back surface at particular incidence angles. A first 2D image source provides a foreground image and a second 2D image source to provide a background image. First and second liquid crystal displays may be arranged with display surfaces proximate to top and bottom edges of the beam combining film and at angular offsets to emit light corresponding with a 2D image stream onto the back surface of the beam combining film at one of the film's incidence angles. The 2D image streams striking the back surface of the film are combined by the film and transmitted from the front surface as a single autostereoscopic video image.
