Hyperspectral Imagers

"Hyperspectral imagers undertake Hyperspectral Imaging (HSI) - a technique that analyzes a wide spectrum of light instead of just assigning primary colours (red, green, blue) to each pixel. The light striking each pixel is broken down into many different spectral bands in order to provide more information on what is imaged. The algorithms and the image processing methodologies associated with HSI are a product of military research, and were primarily used to identify targets and other objects against background clutter. In the past, HSI has seen civil applications, and has particularly been useful in satellite technology."
