Patents by Inventor Jay C. Hanan

Jay C. Hanan 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).

  • Holographic memory using beam steering
    Patent number: 7251066
    Abstract: A method, apparatus, and system provide the ability for storing holograms at high speed. A single laser diode emits a collimated laser beam to both write to and read from a photorefractice crystal. One or more liquid crystal beam steering spatial light modulators (BSSLMs) steer a reference beam, split from the collimated laser beam, at high speed to the photorefractive crystal.
    Type: Grant
    Filed: August 4, 2006
    Date of Patent: July 31, 2007
    Assignee: California Institute of Technology
    Inventors: Tien-Hsin Chao, Jay C. Hanan, George F. Reyes, Hanying Zhou
  • Holographic memory using beam steering
    Patent number: 7149014
    Abstract: A method, apparatus, and system provide the ability for storing holograms at high speed. A single laser diode emits a collimated laser beam to both write to and read from a photorefractice crystal. One or more liquid crystal beam steering spatial light modulators (BSSLMs) or Micro-Electro-Mechanical Systems (MEMS) mirrors steer a reference beam, split from the collimated laser beam, at high speed to the photorefractive crystal.
