Advancing Medical Imaging with Ultra-Thin Detector

Researchers at the University of Maryland (UMD), College Park, say that their work could lead to a generation of light detectors that can see below the surface of bodies. Using graphene, their prototype detector is able to view an extremely broad band of wavelengths, including terahertz waves, which fall between microwaves and infrared waves. The light in terahertz wavelengths can pass through materials that we normally think of as opaque, such as skin.
