T-ray vision

摘要

A terahertz or T-ray imaging system that can map the inside of an object in 3D has been developed in the US. The researchers hope to expand the small prototype setup to a size feasible for security roles, such as airport luggage scanning. As X-ray machines only create images from one perspective, some of the contents of a suitcase can remain hidden. Being able to scan in 3D could enable security staff to spot items concealed among other contents.
