John Federici, a physics professor at NJIT, sees the use of terahertz rays as a critical technology in the defense against suicide bombers and other terrorist activities.  Federici and his research team recently described experimental results from a digital video camera invented in their laboratory that uses a terahertz imaging system.  One day such a device could be used to scan airport passengers quickly and efficiently. “Video-Rate terahertz Interferometric and Synthetic Aperture Imaging” appeared in Applied Optics (July, 2009).  >>
