This work presents the study of KDP (Key Data Parameters) for the calibration of the instrument FLORIS (FLuORescence Imaging Spectrometer) onboard of the satellite FLEX
(FLuorescence EXplorer). FLORIS is an hyperspectral imager that will be calibrated at CSL (Centre Spatial de Liège) which is a research center of the University of Liège. This project explains the calibration philosophy applied for this instrument, and focuses on the computation of KDP related to the non-linearity of the detector. The first part presents the fluorescence mission, mission architecture and FLORIS overview and design. The second part explains the calibration philosophy that will be applied to FLORIS at CSL and will also introduce the concept of KDP.
The last part focuses on the computation of the KDP related to the non-linearity of the detector. As there are no measurements available for FLORIS, the calibration will be done with the measurements of another instrument: 3MI. Four different methodologies are applied and compared for computing KDP related to the non-linearity.
