New laser tuning method from MIT promises smarter airport scanners
MIT researchers have developed a new way to tune the frequency of lasers that operate in the terahertz spectrum
Article Summary
New research out of MIT could lead to smarter airport scanners able to detect the presence of drugs and explosives. At the heart of the development is a new approach to laser tuning designed to harness terahertz rays so that they can be used to determine an object's chemical composition.
