Sub-mm-wave Imaging

We have developed Focal Plane Arrays (FPAs) using micro antenna structures as sensing elements responding to waves with wavelengths greater than 100 micron in the sub-millimeter wave (or teraHZ) domain for imaging objects behind walls, embedded in debris or under human skin. This technology leads to advanced imaging sensors for through-wall surveillance in fighting terrorists, through-skin imaging of foreign objects embedded in human tissue or through clothing to detect hidden narcotics, weapons or alcohol.
