    • Linear polarization signatures of atmospheric dust with the SolPol direct-sun polarimeter 

      Daskalopoulou, Vasiliki; Raptis, Panagiotis I.; Tsekeri, Alexandra; Amiridis, Vassilis; Kazadzis, Stelios; Ulanowski, Zbigniew; Charmandaris, Vassilis; Tassis, Konstantinos; Martin, William (2023-10-12)
      Dust particles in lofted atmospheric layers may present a preferential orientation, which could be detected from the resulting dichroic extinction of the transmitted sunlight. The first indications were provided relatively ...

    • Mitigating Modal Noise in Multimode Circular Fibres by Optical Agitation using a Galvanometer 

      Ghosh, Supriyo; Boonsri, Chantira; Martin, William; Jones, Hugh R. A.; Choochalerm, Piyamas; Usher, Sarah; Yerolatsitis, Stephanos; Wocial, Thomas; Wright, Thomas (2024-01-02)
      Modal noise appears due to the non-uniform and unstable distribution of light intensity among the finite number of modes in multimode fibres. It is an important limiting factor in measuring radial velocity precisely by ...
