The AVIRIS instrument has been designed to do high spectral resolution remote sensing of the Earth. Utilizing both silicon and indium antimonide line array detectors, AVIRIS covers the spectral region from 0.41 pm to 2.45 pm in 10-nm bands. It was designed to fly aboard NASA's U2 and ER2 aircraft, where it will simulate the performance of future spacecraft instrumentation. Flying at an altitude of 20 km, it has an instantaneous field of view (IFOV) of 20 m and views a swath over 10 km wide. With an ability to record 40 minutes of data, it can, during a single flight, capture 500 km of flight line.© (1987) COPYRIGHT SPIE--The International Society for Optical Engineering.
