Detection and identification of explosives and illicit drugs by terahertz spectroscopy technology
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010Terahertz(THz)radiation, which occupies a relatively unexplored portion of the electromagnetic spectrum between mid-infrared and microwave bands, offers innovative sensing and imaging technologies that can provide information unavailable through conventional methods such as microwave and X-ray techniques.
