Near-infrared Linear Polarization of Ultracool Dwarfs
, 2011 We report on near-infrared J- and H-band linear polarimetric photometry of eight ultracool dwarfs (two late-M, five L0-L7.5, and one T2.5) with known evidence for photometric variability due to dust clouds, anomalous red infrared colors, or low-gravity ...

Polarimetric Evidence of Non-Spherical Winds [PDF]
, 1999 Polarization observations yield otherwise unobtainable information about the geometrical structure of unresolved objects. In this talk we review the evidences for non-spherically symmetric structures around Luminous Hot Stars from polarimetry and what we

Learning-based denoising for polarimetric images
Optics Express, 2020 Based on measuring the polarimetric parameters which contain specific physical information, polarimetric imaging has been widely applied to various fields. However, in practice, the noise during image acquisition could lead to the output of noisy polarimetric images.

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Dual‐Polarization‐Sensitive Organic Photodetectors for Real‐Time Polarimetric Imaging
Laser &Photonics Reviews, EarlyView.Bias‐switchable organic photodetectors with orthogonally stacked uniaxially oriented polymer layers enable dual‐polarization detection and real‐time polarimetric imaging. This scalable, template‐free strategy achieves a high dichroic ratio (>11), rapid response (>500 Hz), and detectivity up to 1013 Jones.

Annals of Applied Biology, EarlyView.We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...
