The Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) measures the spectral range from 370 nm to 2510 nm with better than 10 nm sampling. AVIRIS is a whiskbroom imaging spectrometer with exceptional cross-track spectral uniformity. The Spectral-IFOV-Uniformity is also near 100%. The radiometric range of AVIRIS is from 0 to the maximum Lambertian reflected radiance. With F/1 optics and minimal obscuration, AVIRIS measures high precision spectra with signal-to-noise ratios in excess of 1500:1 in the visible (@ 600 nm) and 600:1 in the short-wavelength-infrared (@ 2200nm). The spatial swath of AVIRIS is 34 degrees with a 1 milliradian instantaneous-field-of-view (IFOV). AVIRIS operates on a range of airborne platforms offering spatial resolution from 2 to 20 meters. This poster presents details of the current measurement performance of AVIRIS as well as past, present, and expected future contributions to NASA's Biodiversity, Terrestrial Ecology, and Related Applied Sciences.
