Abstract: We have developed new algebraic tools based upon the symmetries of Mueller matrices that allow us to circumvent those problems while keeping the adjective polarization-free for our telescopes and not requiring expensive and delicate calibrations. The basic concept is to modulate entrance polarization into the eigenvectors of the system so that polarization information arrives unscathed at the analyzing beamsplitters, placed at the instrument or detector level. I will describe the basic concept, its application to THEMIS and the propositions for EST.
