 Hyperspectral imaging

Imaging in many narrow, usually adjacent wavelength bands. Relative to broad-band multispectral imaging, it can resolve narrower mineral absorption features in spectral reflectance, helping distinguish surface lithologies, at the cost of data volume and often reduced signal per band.

Hyperspectral imaging is a technology that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging, which uses just a few bands of light (such as red, green, and blue), hyperspectral imaging collects data in many narrow bands, often hundreds or even thousands of them, across the visible, near-infrared, and sometimes even into the thermal infrared ranges.
