Design and first test results of the Finnish airborne imaging spectrometer for different applications (AISA)

During the year 1992 a prototype airborne imaging spectrometer is developed in Finland. The instrument is in the first place developed for technology demonstration, performance verification and algorithm development. The first tests of the AISA (Airborne Imaging Spectrometer for different Applications) are performed during the end of 1992 and the beginning of 1993. This paper describes the instrument design concept and will list the first test results. The instrument has 288 spectral channels, a spatial resolution of 384 pixels across track and is through software flexible programmable. Targets during the development have been simplicity and robustness. Applications can be found in forestry, ecology, hydrology, geology, agriculture etc
