Based on the absorption and scattering properties of materials with X-rays—X-rays are generated by an X-ray tube, where an electric current heats the cathode, releasing free electrons. These free electrons are then accelerated toward the anode under high voltage, where they are converted into X-rays. The X-rays are directed onto the sample surface, enabling them to penetrate the material and reveal its absorption and scattering characteristics.
High density → Absorbs more → Develops bright white
Low density → Less absorption → Develops darker tones
