Spectral density response functions for modulated polarimeters.

Applied Optics, 2015
Conventional imaging devices are often compared using their optical transfer functions (OTFs) in space and their impulse responses in time. Modulated polarimeters cannot be directly compared this way, since they are frequency multiplexed.

Polarization of X-ray lines from galaxy clusters and elliptical galaxies - a way to measure tangential component of gas velocity

, 2010
We study the impact of gas motions on the polarization of bright X-ray emission lines from the hot intercluster medium (ICM). The polarization naturally arises from resonant scattering of emission lines owing to a quadrupole component in the radiation ...

Measurement of the polarization state of light using an integrated plasmonic polarimeter

Nanophotonics, 2012
Plasmonics has started to facilitate the replacement of bulky optical components in optical systems by compact nanometallic elements that perform the same function. This allows for a natural and very dense integration with electronic devices.

A high-precision polarimeter

, 1999
We have built a polarimeter in order to measure the electron beam polarization in hall C at JLAB. Using a superconducting solenoid to drive the pure-iron target foil into saturation, and a symmetrical setup to detect the Moller electrons in coincidence ...

Feasibility of the Spin-Light Polarimetry Technique for Longitudinally Polarized Electron Beams

EPJ Web of Conferences, 2014
A novel polarimeter based on the asymmetry in the spatial distribution of synchrotron radiation (SR) will make for a fine addition to the existing Møller and Compton polarimeters.

AGATA modules as Compton polarimeters for the measurement of gamma-ray linear polarisation

EPJ Web of Conferences, 2014
The ability of a cluster of three segmented Ge crystals (“AGATA module”) acting as a Compton polarimeter to measure the linear polarization of gamma rays has been investigated at an energy close to 511 keV.

Optimal Summary Statistics for X-ray Polarization

The Open Journal of Astrophysics
We develop two new highly efficient estimators to measure the polarization (Stokes parameters) in experiments that constrain the position angle of individual photons such as scattering and gas-pixel-detector polarimeters, and analyse in detail a ...
