  • Hadamard multimode optical imaging transceiver
    Patent number: 8300113
    Abstract: Disclosed is a method and system for simultaneously acquiring and producing results for multiple image modes using a common sensor without optical filtering, scanning, or other moving parts. The system and method utilize the Walsh-Hadamard correlation detection process (e.g., functions/matrix) to provide an all-binary structure that permits seamless bridging between analog and digital domains.
    Type: Grant
    Filed: October 10, 2008
    Date of Patent: October 30, 2012
    Assignee: Los Alamos National Security, LLC
    Inventors: Bradly J. Cooke, David C. Guenther, Joe J. Tiee, Mervyn J. Kellum, Nicholas L. Olivas, Nina R. Weisse-Bernstein, Stephen L. Judd, Thomas R. Braun
  • Remote detection of electronic devices
    Patent number: 8275334
    Abstract: An apparatus and method for detecting solid-state electronic devices are described. Non-linear junction detection techniques are combined with spread-spectrum encoding and cross correlation to increase the range and sensitivity of the non-linear junction detection and to permit the determination of the distances of the detected electronics. Nonlinear elements are detected by transmitting a signal at a chosen frequency and detecting higher harmonic signals that are returned from responding devices.
