  • Fourier transform volume holographic spectrometer
    Patent number: 7667882
    Abstract: One embodiment of a system includes a volume hologram for dispersing a general diffuse beam of light provided as input; a detector for receiving and detecting light dispersed by the volume hologram; and a Fourier transforming lens for forming the Fourier transform of the light dispersed from the volume hologram onto the detector. Other systems and methods are also provided.
    Type: Grant
    Filed: October 12, 2005
    Date of Patent: February 23, 2010
    Assignee: Georgia Tech Research Corp.
    Inventors: Ali Adibi, Chao Ray Hsieh, Arash Karbaschi, Omid Momtahan
  • High throughput holographic spectrometer using the multiplexed hologram
    Patent number: 7649660
    Abstract: A sophisticated volume hologram for dispersing an incident optical signal with uniform spectrum over an input plane to an output pattern with non-uniform spatial-spectral information, where the sophisticated volume hologram includes a plurality of holograms that map different input wavelengths into different locations on an output plane. The system further includes a detector for receiving and detecting light dispersed by the sophisticated volume hologram.
