In the post-9/11 world, an envelope may hide disease and a shoe may conceal explosives. Detecting these threats is time-consuming and labor-intensive. According to scientists at the US Army Research Laboratory at Aberdeen Proving Ground in Maryland, laser-induced breakdown spectroscopy (LIBS) promises to ease the burden. In laser-induced breakdown spectroscopy, a solid-state, pulsed laser is focused onto a sample to form a high-temperature plasma. The elemental composition of the sample can be identified by the characteristics of the light emissions from the atoms, ions and molecular...Read full article
