Current solutions in terms of coherent sources of T-rays
either require cryogenic temperatures or are relatively bulky equipments based on optically-pumped materials.
can be focused harmlessly below into the body and capture biochemical signatures of events like the start of cancer.
A new way to create electromagnetie Terahertz (THz) waves or T-rays
developed in research in Singapore and London could make better medical scanners.
After several rises and falls of enthusiasm in terahertz domain during many decades , it seems that at last the T-rays
research and technology has found the real boost during last 10 years.
have properties that make them intriguing to scientists.
are low levels of energy that can pass through smoke, clouds, and some solid materials such as clothing.
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.
are a form of low-level energy naturally emitted from all materials, including rocks, plants and people.
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
, space-based Internet access, WLANs and the leading mobile OS platforms, www.
