摘要： A system for displaying three dimensional (3D) images. The system includes a 3D display operating in a first state to display a 3D image by outputting light into a viewing space and operating in a second state in which the 3D image is not displayed. The system further includes a screen element positioned between the 3D display and the viewing space. The screen element reflects light from the viewing space to appear opaque to a viewer in the viewing space when the 3D display operates in the second state. The screen element transmits the light output by the 3D display, whereby the 3D display image is perceivable by the viewer in the viewing space. The screen element includes a sheet of mesh or netting material that transmits light output by the 3D display through its pores or openings and may be a planar sheet of scrim or tulle.

摘要： 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.

摘要： 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.

摘要： A display system for transforming sunlit and other brightly lit surfaces while being observed by viewers or an audience. The display system includes an optical element switchable between first and second operating states, and the optical element includes a pane that is opaque in the first operating state and transparent in the second operating state. The display system includes a controller operable to switch the optical element between the first and second operating states. Further, the display system includes a background image element positioned adjacent to a first surface of the pane of the switchable optical element. The pane may be a liquid crystal (LC) film, and the controller operates a power source to provide electric current to the LC film to switch the optical element to the second operating state. The display system may include a foreground image element positioned proximate to a second surface of the pane.

摘要： A display system for displaying images on a textured surface. 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.

摘要： A compact mirror-based three-dimensional (3D) display system with a polarizer between the viewer in a viewing space and a beam splitter. The beam splitter may be a half-silvered mirror, and the polarizer may be a circular polarizer that acts to cancel the undesired reflections including that of a viewer. A half prop often will be positioned between the beam splitter and the polarizer. The mirror-based 3D display system may also utilize additional components for creating effects that move in depth and that are in 3D. This may include rotation of the display (or its monitor or display screen) from parallel to an offset angle to allow displayed images to move toward and away from the mirror and not be locked into a plane parallel to and often abutting the mirror. The display system may further include configurations that provide a backdrop image behind the displayed image.

摘要： 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.
