Polarization imaging over sea surface - a method for measurements of Stokes components angular distribution [PDF]

Journal of the European Optical Society-Rapid Publications, 2015
This article describes a method for determining the angular distribution of light polarization over a roughened surface of the sea. Our method relies on measurements of the Stokes vector elements using a polarization imaging camera that operates using ...

Polarization of asteroid (387) Aquitania: the newest member of a class of large inversion angle asteroids

, 2008
We present new imaging polarimetric observations of two Main Belt asteroids, (234) Barbara and (387) Aquitania, taken in the first half of 2008 using the Dual-Beam Imaging Polarimeter on the University of Hawaii 2.2 meter telescope, located on Mauna Kea,

Albedo heterogeneity on the surface of (1943) Anteros [PDF]

, 2009
We have investigated the effect of rotation on the polarization of scattered light for the near-Earth asteroid (1943) Anteros using the Dual Beam Imaging Polarimeter on the University of Hawaii's 2.2 m telescope.

Optical linear polarization in ultra cool dwarfs: A tool to probe dust in the ultra cool dwarf atmospheres

, 2009
Aims.Recent studies have detected linear polarization in L dwarfs in the optical I band. Theoretical models have been developed to explain this polarization. These models predict higher polarization at shorter wavelengths.

Polarization-selective excitation of N-V centers in diamond [PDF]

, 2007
The nitrogen-vacancy (N-V) center in diamond is promising as an electron spin qubit due to its long-lived coherence and optical addressability. The ground state is a spin triplet with two levels ($m_s = \pm 1$) degenerate at zero magnetic field ...

Lensless polarization camera for single-shot full-Stokes imaging

APL Photonics, 2022
Lensless cameras have recently emerged as a compact imaging system based on computational imaging with various multiplexing capabilities. Here, we propose a compact, low-cost, lensless camera that enables snapshot full-Stokes polarization imaging.
