| 20150362651 | METHOD FOR DESIGN AND MANUFACTURING OF OPTICS FOR HOLOGRAPHIC SIGHT - A method for design and fabrication of holographic optical elements for a compact holographic sight is proposed. The method includes use of ray-trace software to design holographic elements having optical power using an intermediate hologram with parameters obtained through minimization of the merit function defining image quality. | 12-17-2015 |
| 20120250150 | Projection Screen for Displaying Two-Dimensional and Three-Dimensional Motion Pictures and Method of Use Thereof - The present disclosure reveals a reflective, front-projection screen designed to faithfully and accurately display the images from state-of-the-art (SOTA) and next-generation 2D and 3D motion-picture projectors, such as those found in large-capacity public movie theaters, home theaters, offices, and for use with portable projection systems for consumer and commercial applications. In particular it discloses cinema-size light shaping 3D projection screens with front-surface microstructures and horizontal viewing angles in the range of 90 to 120 degrees. | 10-04-2012 |
| 20120188791 | SUBSTRATE-GUIDED HOLOGRAPHIC DIFFUSER - A substrate-guided holographic diffuser has a light-guide section configured to in-couple light and transmit the light within itself via total internal reflection. It can also have a brightness enhancement section that recycles non-diffracted light within the light-guide section. A hologram section that receives light from the light-guide section has a holographic structure defining acceptance conditions and is positioned relative to the internally reflected light such that the internally reflected light meets the acceptance conditions of the holographic structure. The internally reflected light is out-coupled by the holographic structure as a projected image of light scattered from a diffuser. | 07-26-2012 |
| 20120170090 | Apparatus and method for collimating diffused light using a compound holographic optical element - A collimator can be made of a compound holographic optical element made of three holographic optical elements. The first reflection holographic optical element will have recorded within it continuous lens configured to receive light from a diffuse light beam and diffract the received light as a first collimated light beam. The second reflection holographic optical element will have recorded within it a regular hologram that is configured to permit the light from the diffuse light source to transmit through it to reach the first reflection holographic element, the second reflection holographic element having within it a second holographically reflective structure configured to receive the first collimated light beam and diffract the first collimated light beam as a second collimated light beam. The third transmission holographic optical element is configured to receive the second collimated light beam and diffract it as a third holographic light beam. | 07-05-2012 |
| 20110157695 | PROJECTION SCREEN FOR DISPLAYING TWO-DIMENSIONAL AND THREE-DIMENSIONAL MOTION PICTURES AND METHOD OF USE THEREOF - The present disclosure reveals a reflective, front-projection screen designed to faithfully and accurately display the images from state-of-the-art (SOTA) and next-generation 2D and 3D motion-picture projectors, such as those found in large-capacity public movie theaters, home theaters, offices, and for use with portable projection systems for consumer and commercial applications. In particular it discloses cinema-size light shaping 3D projection screens with front-surface microstructures and horizontal viewing angles in the range of 90 to 120 degrees. | 06-30-2011 |
| 20110108874 | Method to Provide Microstructure for Encapsulated Hgh-Brightness LED Chips - Encapsulated LEDs can be made by taking a mold tool defining a cavity that defines a lens shape and providing a patterned release film defining the inverse of a microstructure in a surface of the film. The patterned release film is conformed to the cavity of the mold tool. An LED chip is placed in a spaced relationship from the patterned release film in the cavity. A resin is then introduced into the space between the LED chip and the patterned release film in the cavity. The resin is cured in the space between the LED chip and the patterned release film in the cavity while contact is maintained between the patterned release film and the curing resin. The encapsulated LED is then freed from the mold tool and the patterned release film. | 05-12-2011 |
