Abstract
The use of diffusers in space-based spectrometers leads to the creation of speckles, in the entrance slit. Due to these speckles, unwanted modulations in the measured spectral data are observed. We explain the origin of these unwanted modulations, which we refer to as speckle-induced spectral features or, in short, spectral features. A single value is introduced that can be used to indicate the effect of the speckle-induced spectral features, the spectral feature amplitude (SFA). Measurement and modeling of the SFA parameter on aluminum diffusers are presented.
