can be focused harmlessly below into the body and capture biochemical signatures of events like the start of cancer.
have properties that make them intriguing to scientists.
Unlike microwaves and X-rays, scientists didn't know until very recently how to make terahertz radiation, also known as T-rays
, explains Daniel Mittleman, an electrical engineer at Rice University in Houston.
Then, it collects the T-rays
and processes them to form images that reveal concealed objects hidden under a person's clothing.
Department of Energy's Argonne National Laboratory, along with collaborators in Turkey and Japan, have created a compact device that could lead to portable, battery-operated sources of T-rays
, or terahertz radiation.
The Navy is also interested in ultraviolet and terahertz light, or T-rays
, which the FEL can produce at world-record powers.
The scanners use the little-known T-rays
- terahertz radiation - to penetrate clothing and identify hidden explosives like those used by the London suicide bombers including Mohammad Sidique Khan.
The book also covers multimedia messaging, T-rays

are electromagnetic waves with a wavelength shorter than microwave but longer than infrared.
London, Jan 21 ( ANI ): Biomedical detective devices similar to the 'tricorder' scanner used in 'Star Trek' may be possible someday, say scientists who have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays
- the technology behind full-body security scanners.
are based on the terahertz region of the electromagnetic spectrum, which is defined by frequencies from 0.
