Bomb Detection: By Laser – MIT and Princeton Build a Terahertz Spectroscopy System
Researchers at MIT and Princeton have built a new laser-powered terahertz spectroscopy system capable of detecting chemicals used in explosives. Terahertz spectroscopy is the measurement of electromagnetic radiation between the frequencies of microwaves and infrared. Scientists have long realized the radiation’s potential for bomb detection, but traditional terahertz spectroscopy systems are bulky and use lots […]
