T-Ray Camera Speed Boosted a Hundred Times Over

Scientists from University of Warwick and Chinese University of Hong Kong have refined a new type of camera to make it a hundred times faster than the previous state of the art. The technique utilizes terahertz radiation, or Trays, that sit in-between infrared and Wi-Fi on the electromagnetic spectrum. Trays can ‘see’ through common materials such as plastics and clothing but are non-ionizing — making them ideal for non-invasive screening.
