Development of a new sensor module for hyperspectral polarimetric measurements

The Institute for Space Sciences at the Free University Berlin has built an instrument for hyperspectral measurements (FUBISS). A new polarization entrance optics and a motion control unit is going to be adopted to that system to open up the possibility to derive hyperspectral polarization measurements in the atmosphere in the spectral region from the visible to the near IR. The system is ground based and includes the ground based version of the aureole Sun-Photometer FUBISS-SIRA and FUBISS-ASA. The polarization measurements enable the calculation of the stokes vector and the degree of polarization measurements enable the calculation of the stokes vector and the degree of polarization and angle at predefined incident viewing angles. One possible application will be the characterization of aerosols by retrieving profiles of their optical and micro physical properties.
