ColourLex is being supported bythecogitofoundation. As any imaging instrument, spectral imaging instruments have a limited spatial resolution - often determined by the number of pixels of some kind of image sensor.. Multispectral imaging is valuable to forensic teams because it is a non-contact, non-destructive way to analyse evidence. Some pigments such as cadmium yellow fluoresce in the infrared region and can be detected in this manner. At 1000nm, the difference in how paper and ink reflect infrared light makes the text clearly readable. Prior to the development an extensive patent screening and IP landscaping has been done for the particular application. The images can be the usual reflexive images or they can also be recorded in transmission where the light which passes through the painting is recorded. Multispectral imaging helps farmers minimize the use of sprays, fertilizers and irrigation, while increasing the yield from their fields.
