Paper Abstract

The presence of structures, as observed in real data from earth observing satellites, that are due to the on-board diffusers are discussed. These structures are shown to be caused by the speckles created by the diffusers in the entrance slit of the spectrometer. A dedicated set-up for the study of these spectral features will be presented together with results on different types of diffusers, i.e. surface diffusers and volume diffusers. Finally, methods to reduce the amplitude of the spectral features will be presented. These methods become more important since the use of infra red channels at high spectral resolutions is aimed for in future missions.
