SWIR Spectral Imaging
SWIR Hyperspectral Imaging
Reflectance Imaging Spectroscopy (RIS)

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 SWIR spectral region of the instrument (930-2500nm), the spectral features primarily show overtones associated with molecular vibrational modes, making it sensitive to organic and synthetic materials as well as providing more definitive identification for some inorganic materials. In the remote configuration, high spectral and spatial resolution scans of a region can be collected at large stand-off distances, enabling the collection of data from areas at inaccessible heights. The system is placed on a computer controlled motorised pan/tilt stage, allowing convenient and automated imaging of any areas of a monument/ object from one position on the ground without moving the instrument​. In indoor and low light environments, a tungsten halogen light source is used to provide controlled illumination. In situations requiring remote sensing, a tungsten halogen light with long-range projection capability is used to provide sufficient illumination at long distances.
