densitetsmodulation
Densitetsmodulation, or density modulation, is a general term for techniques that deliberately vary the density of a material, a medium, or a signal in order to influence how it interacts with probing waves, light, or measurement systems. The modulation can be spatial, temporal, or spectral and is achieved by changing composition, layering, porosity, thickness, or by controlling how a sensing or imaging system samples and processes information.
In medical and industrial imaging, density modulation is often used to optimize image quality and reduce exposure.
In materials science and manufacturing, density modulation describes the deliberate variation of density within a structure,
In display, printing, and imaging, density modulation underpins tone reproduction methods like halftoning, where a continuous
Common considerations include calibration, potential artifacts at sharp density transitions, and the need for specialized hardware
