New 'T-ray' Space Camera Also Sees Through Clothes, Walls
A new British science program aims to produce cameras for use in space that are so sensitive they will see through fog, smoke and even walls and clothing. The technology will detect an obscure yet ubiquitous form of radiation known as terahertz waves, also called T-rays. Similar cameras are also expected to have applications in airport security and medicine. One camera, already built by a company called QinetiQ and working in so-called millimetric waves, has demonstrated the ability to eerily peer through clothes and reveal a concealed weapon -- as well as much of a person's body. The image shows far more detail than an infrared camera, which detects heat.
