The prototype device uses terahertz radiation, the band of electromagnetic radiation between microwaves and infrared light. For instance, terahertz rays can distinguish between ink and blank paper in a way that X-rays cannot. They can also scan across depths to yield higher resolution images than ultrasound can accomplish, according to the researchers.
