Paper Abstract

To increase the accuracy of earth-observation spectro-imagers, it is necessary to achieve high levels of depolarization of the incoming beam. The preferred device in space instrument is the so-called polarization scrambler. It is made of birefringent crystal wedges arranged in a single or dual Babinet. Today, with required radiometric accuracies of the order of 0.1%, it is necessary to develop tools to find optimal and low sensitivity solutions quickly and to measure the performances with a high level of accuracy.
