Robert H. Kingston 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).

  • Spatial light modulator
    Patent number: 4865427
    Abstract: Spatial light modulators which use a substrate having a buried channel charge-coupled device (CCD) formed therein, wherein the amount of charge in the charge storage wells associated with the electrodes of the CCD is controlled by an electrically or optically addressed data signal. The level of charge in such charge storage wells controls the electric field beneath the electrodes so that the intensity of electromagnetic energy (e.g., light) directed through The CCD is spatially modulated by the charge levels in the charge storage wells in accordance with the Franz-Keldysh electroabsorption effect.
    Type: Grant
    Filed: August 6, 1987
    Date of Patent: September 12, 1989
    Assignee: Massachusetts Institute of Technology
    Inventors: Robert H. Kingston, Frederick J. Leonberger
