Spectral mapping is a research area that involves analyzing and displaying the spectral information of a given material or substance. This can be done using various techniques such as spectroscopy, imaging spectroscopy, or hyperspectral imaging. By mapping the different wavelengths of light that are absorbed or emitted by a material, researchers can gain insights into its chemical composition, structural properties, and other characteristics. Spectral mapping is commonly used in fields such as remote sensing, environmental monitoring, materials science, and biomedical research.
