Helically Flexible Boron‐Dipyrromethenes for Solution‐Processed Isotropic Films With Preserved Chiral Exciton Coupling

open access: yesAggregate, Volume 7, Issue 8, August 2026.
Accessible and chiroptically tunable helically chiral boron‐dipyrromethene dimer dyes enable the fabrication of solution‐processed isotropic neat thin films that retain sharp visible electronic circular dichroism signatures from solution. This platform establishes a direct molecule‐to‐material relationship and provides a robust foundation for the ...

Polarimeters for the Detection of Anisotropy from Reflectance

open access: yesMicromachines
Polarimetry is used to determine the Stokes parameters of a laser beam. Once all four S0,1,2,3 parameters are determined, the state of polarisation is established.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

open access: yesAstronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Compensation of Dispersion in Sinuous Antennas for Polarimetric Ground Penetrating Radar Applications

open access: yesRemote Sensing, 2019
In order to improve the accuracy of subsurface target classification with ground penetrating radar (GPR) systems, it is desired to transmit and receive ultra-wide band pulses with varying combinations of polarization (a technique referred to as ...

Investigation into Different Polarimetric Features for Sea Ice Classification Using X-Band Synthetic Aperture Radar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Satellite-borne synthetic aperture radar has proven to be a valuable tool for sea ice monitoring for more than two decades. In this study, we examine the performance of an automated sea ice classification algorithm based on polarimetric TerraSAR-X images.

Comparison of Methods for Classification of Land Cover using Poarimetric SAR data [PDF]

open access: yes, 2006
Polarimetric SAR data are coherent by nature of the principle of operation. However, most often incoherent ap-proaches are chosen for the post-processing in order to apply conventional averaging and statistical methods.

Introducing Partial Polarimetric Layers into a Curvelet-based Change Detection [PDF]

open access: yes, 2010
In this article a new change detection approach for polarimetric SAR data is presented. The further development of an already published change detection approach based on Curvelet transform for single polarized SAR images is combined with partial ...
