TeraView has recently premiered the abilities of Terahertz light to detect plastic explosive, even through multiple layers of clothing and including the explosive PETN, which was carried undetected onto an aeroplane by the Detroit bomber. Terahertz light isn’t dangerous and is non-invasive. It simply uses the waves between radio waves and light waves to identify explosive materials, without the need for human interaction. Terahertz light is going to be a great tool for airport security!
