A camera that can see through clothes and skin without x-rays could soon be providing low-cost, rapid and safe screening for disease and tissue damage.

The camera, currently in development by scientists in Oxfordshire, England detects ultra-high frequency waves, called terahertz waves or t-rays, given off by all objects. It does not expose patients to potentially harmful radiation.

Just below infrared in the energy spectrum, terahertz waves aren’t a new finding for scientists. But the technology to detect them has been complicated and expensive. Betterhumans
