  • Detection beyond the standard radiation noise limit using spectrally selective absorption
    Patent number: 8629398
    Abstract: High sensitivity thermal detectors that perform beyond the blackbody radiation noise limit are described. Thermal detectors, as described herein, use spectrally selective materials that absorb strongly in the wavelength region of the desired signal but only weakly or not at all in the primary thermal emission band. Exemplary devices that can be made in accordance with the present invention include microbolometers containing semiconductors that absorb in the MWIR and/or THz range but not the LWIR.
    Type: Grant
    Filed: May 29, 2009
    Date of Patent: January 14, 2014
    Assignee: The Regents of the University of Minnesota
    Inventors: Joseph J. Talghader, Ryan P. Shea, Anand S. Gawarikar
