A hyperspectral camera is an imaging device that, unlike a conventional camera, records images in many narrow and continuous bands of light wavelengths. While a classic camera captures only three basic colors (red, green, and blue), a hyperspectral sensor captures dozens to hundreds of them, even in areas invisible to the human eye, such as infrared radiation. The result is a data cube where each image pixel contains complete spectral information, i.e., a record of how a given point on the surface reflects light across the entire spectrum. Thanks to this light "fingerprint," materials can be identified and their condition analyzed using drones. It finds use, for example, in precision agriculture for monitoring crop health, in ecology for pollution detection, or in geology for mapping mineral resources.
