Hyperspectral Imaging

Principles of Spectral Imaging

Spectral imaging includes capturing images at various wavelengths, starting from ultraviolet (UV) to near-infrared (NIR) and occasionally reaching further. Every pixel in the picture holds a spectral signature that demonstrates its reflective or emitting properties throughout the spectrum. Through the examination of these spectral signatures, experts and professionals are able to detect distinct characteristics and trends that cannot be seen with the human eye....
