Paper Abstract

Terahertz (THz) radiation, which occupies a large portion of the electromagnetic spectrum between infrared and microwave bands, offers innovations imaging and sensing technologies that can provide information not available through conventional methods such as microwave, X-ray imaging and NMR(nuclear magnetic resonance). T-ray imaging can give not only the density picture but also the phase information within the frequency domain. T-ray imaging has several advantages over other sensing and imaging techniques, so it has many important scientific, industrial and medical applications. In this paper, we study the feasibility of using THz sensing and imaging for mine detection. The principal features of THz radiation and its unique advantage in mine detection are investigated. Some difficult issues, which are not resolved yet, are discussed. The military applications and development trend of the THz spectroscopy are briefly forecasted.
