Hyperspectral Imaging

Hyperspectral imaging (HSI) is a technique that analyses a wider spectrum of light instead than just assigning primary colours (red, green, blue) to each pixel.

The light striking the pixels in an array is broken down into many different spectral bands in order to provide reflectance information on what is being imaged. Hyperspectral imaging provides identification of materials and specific chemicals thanks to the unique spectral signatures acquired by the pixels generating the image of a scene.

Hyperspectral is useful technique for food and plastic sorting as well as for crop and geological surveys.
