Laser-Guided Terahertz Imaging (1 of 2) (video) Boston College Loading video... Caption A new method for single-pixel terahertz (THz) imaging developed by Boston College researchers uses a set of instructions delivered by a laser beam to tune THz waves in order to produce new types of THz images. During the imaging method devised by the team, THz waves pass through an object (a); then they strike a silicon semiconductor (b) given specific instructions about how to sample the image; that data is passed along in order to digitally reconstruct an image (c) of the original object in just a few seconds.
