The airborne imaging spectrometer ROSIS has been designed for environmental investigations. The spectral resolution is 5 nm within a spectral range from 400 to 900 nm. The ground pixel size is 2.2 m x 2.2 m at a flight altitude of 4 km. To meet the design and radiometric requirements, the Thomson TH 7884 CCD matrix sensor was selected. Operating the TH 7884 in the frame transfer mode the image size is 500 x 256 picture elements. To gain the required spectral information we need only 85 lines of this image. To achieve the 2.2 m ground pixel size resolution in flight direction (pushbroom system) about 85 frames/second have to be read out. For this we applied new readout techniques as described in this paper.
