T-rays technology could help develop Star Trek-style hand-held medical scannersLondon UK (SPX) Jan 23, 2012 Scientists have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays - the technology behind full-body security scanners. The researchers behind the study, published recently in the journal Nature Photonics, say their new stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the 'tricorder' scanner used in Star Trek. In the study, researchers from the Institute of Materials Re ... read more |
