Patents by Inventor Robert M. Merritt

Robert M. Merritt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical component adjustment for mitigating tolerance sensitivities
    Patent number: 6172816
    Abstract: Projection lenses and projection lens systems are telecentric between an illumination subsystem and a set of imagers. The lenses and systems can exhibit color fringing correction, uniform imager illumination, athermalization, and component articulation for improved imaging. The lenses and systems may be employed in display apparatuses, such as folded display apparatuses that have decreased footprint size, but long effective projection lengths.
    Type: Grant
    Filed: October 23, 1998
    Date of Patent: January 9, 2001
    Assignee: Duke University
    Inventors: Biljana Tadic-Galeb, Robert E. Fischer, Robert M. Merritt
