The retrieval of the faint fluorescence signal from the acquired vegetation spectra is particularly sensitive to straylight. As results, the straylight requirements on the FLORIS instrument are especially stringent. For FLORIS a two-step straylight reduction process has been put in place by the Leonardo-Thales Alenia Space team to achieve this requirement. Careful instrument design and manufacturing are followed by digital processing of the raw instrument data. In this paper we present the feasibility demonstration of the straylight digital correction process, based on simulation of the dedicated data processing and quantitative assessment of the residuals. |
