(ISRAEL NATIONAL NEWS) — The New York Police Department is testing a new device that can detect firearms concealed beneath layers of clothing.
Dubbed “T-Ray,” the machine detects terahertz radiation, a high-frequency electromagnetic natural energy that is emitted by people. It also detects the presence of hidden metal from a distance, The Wall Street Journal reported.
"If something is obstructing the flow of that radiation, for example a weapon, the device will highlight that object," said Commissioner Raymond Kelly, explaining the device Wednesday.
