Polarization properties of photospheric emission from relativistic, collimated outflows [PDF]
, 2014 We consider the polarization properties of photospheric emission originating in jets consisting of a highly relativistic core of opening angle theta(j) and Lorentz factor Gamma(0), and a surrounding shear layer where the Lorentz factor is decreasing as a

Diffraction Focal Position and Vector Diffraction Theory for Micro Holographic Storage Systems
Applied Sciences, 2014 In this study, we proposed a method to determine the optimal focal position for micro-holographic storage systems, using vector diffraction theory; the theory provides exact solutions when the numerical aperture (NA) exceeds 0.6.

Observation of Cosmic Microwave Background Polarization with BICEP [PDF]
, 2009 Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the ...

Polarization independent adaptive microlens with a blue-phase liquid crystal [PDF]
, 2011 A new polarization-independent and fast-response adaptive microlens array using a polymer-stabilized blue phase liquid crystal is proposed. With a curved top electrode and planar bottom electrode, gradient electric fields are generated and lens-like ...

Demo 24-06 Polarization by Double Reflection
, 2001 Polarization of light is obtained by using two reflections from dielectric plates, as in Figure 1. This demonstration illustrates the effect of double reflection on the polarization of an initially unpolarized light beam.

Signatures of Black Hole Spin and Plasma Acceleration in Jet Polarimetry. II. Off-axis Jets
The Astrophysical JournalWe analyze the polarization of optically thin, stationary, axisymmetric black hole jets at scales of order the light cylinder radius. Our work generalizes the face-on results of Z. Gelles et al. to arbitrary viewing inclination.

Primary aberrations in focused radially polarized vortex beams
Optics Express, 2004 We study the effect of primary aberrations on the 3-D polarization of the electric field in a focused lowest order radially polarized beam. A full vector diffraction treatment of the focused beams is used. Attention is given to the effects of primary spherical, astigmatic, and comatic aberrations on the local polarization, Strehl ratio, and aberration ...

The primary structure design of a birefringent lens with the concept of pseudo-chromatic aberration
, 2006 Much attention has been paid to the optical design of a birefringent lens and analysis of its polarization aberration due to its essential application in bifocal interferometric microscopes. To investigate a practical way of designing a birefringent lens
