Ultraspectral Imaging Imaging spectroscopy has many names in the remote sensing community, including imaging spectrometry, hyperspectral, and ultraspectral imaging.
Spectroscopy is the study of electromagnetic radiation.
Spectrometry is derived from spectro-photometry, the measure of photons as a function of wavelength, a term used for years in astronomy. Hyper means excessive, but no imaging spectrometer in use can hardly be considered hyper-spectral, after all, a couple of hundred channels pales in comparison to truly high resolution spectrometer with millions of channels. Ultraspectral is beyond hyperspectral, a lofty goal that has not yet been reached. Terms like laboratory spectrometer, spectroscopist, reflectance spectroscopy, thermal emission spectroscopy, etc, are in common use. The image shown here is a mineral map, where each color is the identification of specific minerals through imaging spectroscopy analysis.
