ThruVision is developing a camera that passively images objects that emit Terahertz, or T-rays.
T-rays are “black body” radiation (between microwave and infrared on the spectrum) naturally emitted from all materials, including people. The camera collects these naturally occurring T-rays and processes them to form images that reveal concealed objects hidden under a person’s clothing without displaying physical body detail, the company says.
