Spectral resolution refers to the ability of a sensor to define finer wavelength intervals. Thus, the finer the spectral resolution, the narrower the wavelength range for a given channel or band.  3, fiche 1, Anglais, - high%20spectral%20resolution%20sensor

AVIRIS is a proven instrument in the realm of Earth Remote Sensing. It is a unique optical sensor that delivers calibrated images of the upwelling spectral radiance in 224 contiguous spectral channels (bands) with wavelengths from 400 to 2500 nanometers. AVIRIS has been flown on two aircraft platforms: a NASA ER-2 jet and the Twin Otter turboprop. ... The main objective of the AVIRIS project is to identify, measure, and monitor constituents of the Earth’s surface and atmosphere based on molecular absorption and particle scattering signatures.  3, fiche 3, Anglais, - airborne%20visible%2Finfrared%20imaging%20spectrometer

During the European Multisensor Airborne Campaign 1994(EMAC 94), the Experimental Synthetic Aperture Radar(ESAR) and the Reflective Optics System Imaging Spectrometer(ROSIS) were flown over an experimental catchment in Belgium. Concurrent to the ESAR overflights, field data were collected in two subcatchments of the Zwalmbeek. The main objective of this remote-sensing experiment was to retrieve spatial information of surface soil moisture content.  2, fiche 5, Anglais, - reflective%20optics%20system%20imaging%20spectrometer

Imaging spectrometry ... is the field in remote sensing where sensors acquire image data in many, narrow and contiguous wavebands. The aim is to produce on a pixel by pixel basis radiance and reflectance data, which can be used to model physical properties of the Earth surface. This data forms an addition to subsurface geophysical data.  6, fiche 6, Anglais, - imaging%20spectroscopy

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. However, spectrometry is becoming a term used to indicate the measurement of non-light quantities, such as in mass spectrometry(e. g. Ball, 1995). 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.... Researchers at the USGS Spectroscopy Lab are studying and applying methods for identifying and mapping materials through spectroscopic remote sensing(called imaging spectroscopy, hyperspectral imaging, imaging spectrometry, ultraspectral imaging, etc), on the Earth and throughout the solar system using laboratory, airborne and spacecraft spectrometers.  4, fiche 6, Anglais, - imaging%20spectroscopy
