  • Compressive passive millimeter wave imager
    Patent number: 8941061
    Abstract: A compressive scanning approach for millimeter wave imaging and sensing. A Hadamard mask is positioned to receive millimeter waves from an object to be imaged. A subset of the full set of Hadamard acquisitions is sampled. The subset is used to reconstruct an image representing the object.
    Type: Grant
    Filed: March 28, 2012
    Date of Patent: January 27, 2015
    Assignee: UChicago Argonne, LLC

  • Millimeter wave sensor for far-field standoff vibrometry
    Patent number: 8686362
    Abstract: A millimeter wavelength (MMW) measurement system for remote detection of object characteristics and methods for detecting such characteristics. The MMW measurement system comprises a front-end and an optional signal conditioning component. The MMW front-end includes an oscillator, a transceiver portion, and an antenna for focusing a detection component comprising micrometer level wavelength electromagnetic radiation onto the object. A portion of the electromagnetic radiation reflected by the object is received by the MMW measurement system, which is indicative of a displacement of the object. The MMW system may be configured to detect micrometer level displacement of the object disposed tens of meters from the MMW measurement system. In various embodiments the object may be a natural object, including a human, and the displacement may be indicative of a heart rate and/or a respiratory function.
