System analysis and performance of the new version of the imaging spectrometer ROSIS

摘要: ROSIS is a compact airborne imaging spectrometer which has been developed jointly by German industry and research organisations. The sensor makes use of two-dimensional CCD array for simultaneously 115 spectral bands 512 picture elements perpendicular to the flight direction. spatial resolution 0.56 mrad, range 430-860 nm sampling interval 4 nm. driver design was its application detection fine structures in coastal inland waters. This task determined selection range, bandwidth, number channels, radiometric tilt capability sun glint avoidance. However, can be used just as well monitoring features above land or within atmosphere. It hitherto mainly scientific preparation MERIS flown on ESA’s ENVISAT satellite. However,accurate calibration limited electronic problems. Hence entire system re-designed re-built. analysis laboratory data new shows that these problems have eliminated.
