Amazing stuff! Another advance in microscopy!
E.g. "Images produced using THz radiation are also hyperspectral, meaning that each pixel in the image contains the electromagnetic signature of the corresponding area of the imaged object. This property enables researchers to “visualize” the molecular composition of objects and so distinguish between different materials."
Terahertz microscope produces highly accurate 'ghost' images – Physics World: New device could find applications in areas such as the life sciences, airport security and quality control in manufacturing
