spektriimaging
Spektriimaging is an imaging modality that combines spatial resolution with spectral information by capturing, for each image pixel, a spectrum across a range of wavelengths. The data are typically organized as a three-dimensional cube (x, y, λ), enabling analysis of material composition, chemical states, and functional properties based on spectral signatures.
Various implementations exist. Hyperspectral imaging records dozens to hundreds of narrow spectral bands; multispectral imaging uses
Acquisition involves a dispersive element such as a grating or prism, and a detector array like a
Applications span remote sensing, agriculture, mineralogy, environmental monitoring, medical diagnostics and fluorescence imaging, art conservation, and
Challenges include large data volumes, the need for robust calibration and correction (e.g., atmospheric effects in
