    Polarimetry with Disordered Photonic Structures 
    Juhl, Michael; Leosson, Kristjan (American Chemical Society (ACS), 2019-12-20)
    In conventional Stokes polarimetry, where the polarimetric information is obtained from a series of intensity measurements, stable and accurate measurements typically require the optical elements to be carefully designed. Here, we propose a paradigm shift ...
