spectral imaging
hyperspectral imaging

Reflectance spectral imaging is an efficient way of collecting millions of reflectance spectra over an area (2D spatial and wavelength in the 3rd dimension). In the visible-NIR spectral region, the spectral features primarily show electronic transitions in molecules, which enables the identification of most pigments. With this system, the higher spectral resolution allows for the firm identification of pigments and dyes with sharp spectral features (e.g. cobalt pigments, anthraquinone dyes). In the remote configuration, high spectral resolution and spatial resolution scans of a region can be collected at large stand off distances, allowing data to be collected from areas at inaccessible heights. The system is placed on a computer controlled motorised pan/tilt stage that allows for convenient and automated imaging of any areas of a monument/ object from one position on the ground without moving the instrument.
