Polarization image demosaicking using polarization channel difference prior
Optics Express, 2021 This paper presents a simple, yet effective demosaicking technique using polarization channel difference prior for polarization images captured by division of focal plane imaging sensors. The polarization channel difference prior embodies that high frequency energy of difference between orthogonal channels tends to be larger than that between non ...

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-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 ...
