Optical monitoring of the plant growth status using polarimetry

open access: yesScientific Reports, 2022
Polarimetry is a powerful characterization technique that uses a wealth of information from electromagnetic waves, including polarization. Using the rich information provided by polarimetry, it is being actively studied in biomedical fields such as ...

Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose. [PDF]

open access: yesAdv Mater
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

Stellar Polarimetry: Where Are We and Where Are We Going?

open access: yes, 2012
On the final day of the Stellar Polarimetry conference, participants split up into three "breakout sessions" to discuss the future of the field in the areas of instrumentation, upcoming opportunities, and community priorities.

Ultra-high precision x-ray polarimetry with artificial diamond channel cuts at the beam divergence limit

open access: yesPhysical Review Research, 2020
We report on the use of synthetic single-crystal diamonds for high definition x-ray polarimetry. The diamonds are precision mounted to form artificial channel-cut crystals (ACCs). Each ACC supports four consecutive reflections with a scattering angle 2Θ_{

Polarimetric Evidence of Non-Spherical Winds [PDF]

open access: yes, 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

Characterization of photonic structures using visible and infrared polarimetry

open access: yesEPJ Web of Conferences, 2010
Photonic Crystals are materials with a spatial periodic variation of the refractive index on the wavelength scale. This confers these materials interesting photonic properties such as the existence of photonic bands and forbidden photon frequency ...

Hybrid Dual-Polarization Synthetic Aperture Radar

open access: yesRemote Sensing, 2019
Compact polarimetry for a synthetic aperture radar (SAR) system is reviewed. Compact polarimetry (CP) is intended to provide useful polarimetric image classifications while avoiding the disadvantages of space-based quadrature-polarimetric (quad-pol) SARs.

The growth of interest for astronomical X-ray polarimetry

open access: yes, 2018
Astronomical X-ray polarimetry was first explored in the end of the 60's by pioneering rocket instruments. The craze arising from the first discoveries on stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters on-board

Synthetic Mueller Imaging Polarimetry

open access: yesPhotonics, 2023
The transformation of the state of polarization of a light beam via its linear interaction with a material medium can be modeled through the Stokes–Mueller formalism.
