Paper Abstract

The Ocean Radiometer for Carbon Assessment (ORCA) is a new design concept for the next generation ocean biology and biogeochemistry satellite sensor. The wavelength range will be from the near UV, through the visible and to the Short Wave infrared. The challenge in this design is to remove the polarization effects from the optical performance of this hyper spectral observing instrument. In order to remove any polarization sensitivity during observation, the design calls for a front-end depolarizer that consists of two wedged birefringent magnesium fluoride crystals. Here we discuss the polarimetry measurements performed on this polarization scrambler, the depolarizer design and compare these results with model calculations.
