NYPD testing “T-ray” device to see concealed weapons under clothing

The New York Police Department revealed Wednesday that it was developing a device that would scan people for concealed firearms on their body.

The Wall Street Journal reports Commissioner Raymond Kelly saying the NYPD is testing a T-ray (terahertz radiation) machine. Such technology is increasingly being used in airport scanners because the radiation is considered less harmful than X-ray. As IEEE Spectrum put it in its article a few years ago examining the technology, T-rays go through most materials but reflect off metal.

“If something is obstructing the flow of that radiation, for example a weapon, the device will highlight that object,” Kelly said at an event attended by the New York City Police Foundation, according to the WSJ.
