20080266668 | SLM Projection Display with Series DMD Illuminator - The addition of DMD illumination modulator(s) | 10-30-2008 |
20090128881 | Integrated TIR Prism and Lens Element - Disclosed is an optical component, which comprises a prism element adjacent to a lens element, where the two elements are separated by a small air gap. In disclosed embodiments, the elements have adjacent and parallel surfaces which are substantially planar and which, with the small air gap, operate through Total Internal Reflection (“TIR”) to direct light beams that strike the planar surfaces. Light beams that strike at less than the critical angle are internally reflected, while light beams which strike at greater than the critical angle pass through. The TIR surfaces thereby separate the desired optical signals from the spurious ones. The combined TIR prism lens operates as a single and integrated component which directs desired light beams to a reflective optical processing element such as a Spatial Light Modulator and which focuses the processed light beams as they leave the combined TIR prism lens. | 05-21-2009 |
20090141200 | Multi-Function Light Modulators for Optical Systems - In one embodiment, a method includes transmitting one or more light beams by a first portion of a light modulator formed outwardly from a substrate. The one or more transmitted light beams are spatially integrated. A second portion of the light modulator is formed outwardly from the substrate. The second portion of the light modulator spatially integrates the transmitted light beams. | 06-04-2009 |
20090161040 | POLARIZED LIGHT EMITTING DIODE AND USE THEREOF - Provided is a light emitting diode (LED). The LED, in one embodiment, includes a reflective layer located over a substrate and a quarter wave plate emitter layer located over the reflective layer. The quarter wave plate emitter layer, in this embodiment, is substantially crystalline in nature, and further wherein an extra-ordinary axis of the quarter wave plate emitter layer is located in a plane thereof. The LED, in this embodiment, further includes a transmissive/reflective polarization layer located over the quarter wave plate emitter layer, wherein a transmission direction of the transmissive/reflective polarization layer is oriented at about 45 degrees with respect to the extra-ordinary axis. | 06-25-2009 |
20100053560 | LED PACKAGE HAVING IMPROVED LIGHT COUPLING EFFICIENCY FOR AN OPTICAL SYSTEM AND METHOD OF MANUFACTURE THEREOF - One aspect of an LED package, which is covered by this disclosure, includes at least two LED emitters located on a substrate wherein each of the at least two LED emitters forms an emitting area. The emitting area is substantially equal to a reflective area of the LED package, and the LED package has an optical axis that is substantially non-parallel to an optical axis of each of the at least two LED emitters. | 03-04-2010 |
20100149493 | Shared-Field Projection and Imaging System - According to one embodiment of the present invention a method for capturing images on a screen is disclosed. The method includes directing light from a surface of a spatial light modular to an image field using a projection system; capturing light from the image field using the projection system, the projection system directing at least a portion of the captured light to the spatial light modulator; and directing at least a portion of the received captured light to an image capture system using the spatial light modulator. | 06-17-2010 |
20100149626 | Prism for High Contrast Projection - Prism elements having TIR surfaces placed in close proximity to the active area of a SLM device | 06-17-2010 |
20140240573 | SHARED-FIELD PROJECTION AND IMAGING SYSTEM - According to one embodiment of the present invention a method for capturing images on a screen is disclosed. The method includes directing light from a surface of a spatial light modular to an image field using a projection system; capturing light from the image field using the projection system, the projection system directing at least a portion of the captured light to the spatial light modulator; and directing at least a portion of the received captured light to an image capture system using the spatial light modulator. | 08-28-2014 |
