DURHAM, N.C., Jan. 18, 2013 — Unlike jpeg algorithms, which compress an image after it is taken, a new low-profile metamaterial sensor uses microwave imaging to compress pictures as they are being recorded. The Duke University metamaterial sensor acts as a lens to produce two-dimensional images using fewer components than conventional detectors. The findings suggest that cameras, x-ray scanners and other imaging technologies built with the device could provide a more efficient, versatile and cheaper way to take pictures for applications such as airport security scanners and collision avoidance systems for aircraft,...Read full article
