Method and apparatus for increasing quality and resolution of a projected image |
February 27, 2007 |
| A lens includes mechanical dithering that displaces pixels adjacent to undithered pixels. The dithering, for example, precisely places pixels above, below, and on both sides of the undithered pixel. Image data is supplemented with interpolation and/or new data in additional pixel loc |

Pathlength matched beam splitter and method and apparatus for assembly |
February 28, 2006 |
| Pathlength matched optical devices (such as beam splitters) are produced by viewing optical paths through the optical devices and adjusting relative positions of optical components of the optical devices until the viewed optical paths are equivalent. The optical paths begin at markings |

Design of prism assemblies and kernel configurations for use in projection systems |
June 21, 2005 |
| Kernels are designed in different configurations based on design properties of an enclosure or other requirements. A prism assembly having various types of filters, waveplates, beam splitters (e.g., path length matched beam splitters) and/or other optical components are provided to s |

Method and apparatus for packaging optical elements |
March 29, 2005 |
| An optical element is disposed between cover glasses, and an optical coupling liquid is injected between the optical element and the cover glasses to form an optical package. An adhesive provides a liquid tight seal between the cover glasses. The optical element is a retarder, filter, |

Method and apparatus for mounting liquid crystal on silicon (LCoS) and other sensitive devices |
September 28, 2004 |
| A device package has a bezel attached to a carrier. The bezel extends toward a surface of an optical component to which a device mounted in the carrier is attached. The bezel extends in a direction and to a distance that allows the bezel to act as a guide for a dislodging tool. The d |
