Dual polarization split lenses
Optics Express, 2017 We report the realization of polarization sensitive split lens configurations. While split lenses can be used to easily generate different types of controlled structured light patterns, their realization has been limited so far to scalar beams. Here we propose and experimentally demonstrate their generalization to vectorial split lenses, leading to ...

Hydrometeor partitioning ratios for dual-frequency space-borne and polarimetric ground-based radar observations [PDF]
Atmospheric Measurement TechniquesConventional radar-based hydrometeor classification algorithms identify the dominant hydrometeor type within a resolved radar volume, while newer techniques estimate the proportions of individual hydrometeor classes (hydrometeor partitioning ratios, HPRs)
