  • Nondestructive imaging using a split-ring resonator sensing apparatus
    Patent number: 11137359
    Abstract: A defect sensing apparatus is configured to identify defects or targets in materials. A further aspect of the defect sensing apparatus includes a reference split-ring resonator coupled to the microstrip. The defect sensing apparatus includes a reference split-ring resonator located on a reference side of the microstrip and a first sensing split-ring resonator located on a sensing side of the microstrip.
    Type: Grant

  • Eddy current inspection system
    Publication number: 20100045276
    Abstract: An innovative method is provided for assessing structural integrity of a sample. The method comprises: capturing a signal indicative of magnetic flux density caused by an Eddy current flowing in the sample; extracting an envelope of the captured signal using a demodulation scheme; sampling the envelope at a frequency that is lower than the frequency of the excitation current signal which generated the Eddy current; and examining the sampled envelope to assess structural integrity of the sample.

  • Tomographic imaging system using a conformable mirror
    Publication number: 20060239403
    Abstract: A tomographic imaging system comprising a source array emitting rays, a deformable mirror reflecting the rays emitted by the source array, and a detector array receiving the electromagnetic rays emitted by the source array and reflected by the deformable mirror. An object can be positioned between the deformable mirror and the detector array and the deformable mirror can be deformed to a plurality of configurations to form a tomographic image of the object. The system can also be used in radiation therapy.
