New technique doubles resolution of near-field terahertz imaging

(Phys.org)—A team of researchers with members from the University of Exeter, the University of Glasgow and QinetiQ, all in the U.K. has found a way to effectively double the resolution offered by near-field terahertz imaging. In their paper published in the journal Science Advances, the team describes how the technique works and some of the applications that might be bettered through its use.
