During the last three decades, hyperspectral imaging (HSI) has grown from being an expensive research-oriented technique to one that is applicable for a wide range of scientific and industrial applications such as in food production, during forensic analysis, art and art conservation, environmental monitoring, and many others.
The ability of hyperspectral imaging to identify and quantify materials in a non-destructive and non-invasive manner has led to uptake in many new applications, and has allowed it to be developed into a fast and reliable technique to - for example - measure, inspect, grade and sort food products, analyse chemical composition of pharmaceuticals, analyse degradation in the most fragile artwork, and even identify rare earth elements based on their spectral features.
