HTTP:: New Airport Scanner Detects Dangerous Liquids
--------
Scientists at the Forschungszentrum Juelich, in Germany, announce the development of a new method of scanning liquids in airports that reduces the waiting time and is far more effective at detecting substances that may be combined to form bombs than any other existing method. If put to commercial use, the new scanner could have the beneficial effect of lifting the ban on liquids being carried into airplanes. The technology is entirely light-based, and can identify a wide array of liquids in just fractions of a second, the BBC News reports. The German team recently published details of the new system in the latest issue of the journal Superconductor Science and Technology. The innovation also has another major advantage over other existing technologies in the fact that it can work extremely fast and with high accuracy. Other methods, such as nuclear magnetic spectroscopy, either take too long to scan the luggages, or are too expensive for large-scale implementation. The re!
cently devised method has been dubbed Hilbert spectroscopy, and it is able to supply its operators with a firm result in just one fifth of a second. In many research fields, the properties of materials are determined based on the way they reflect light. Each and every substance, and indeed everything in the Universe (with the exception ...
