Data Reduction Techniques for High Contrast Imaging Polarimetry. Applications to ExPo

, 2011
Imaging polarimetry is a powerful tool for detecting and characterizing exoplanets and circumstellar environments. Polarimetry allows a separation of the light coming from an unpolarized source such as a star and the polarized source such as a planet or ...

An X-ray polarimeter for hard X-ray optics [PDF]

, 2006
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

Dual-Polarization Radar Fingerprints of Precipitation Physics: A Review

Remote Sensing, 2022
This article reviews how precipitation microphysics processes are observed in dual-polarization radar observations. These so-called “fingerprints” of precipitation processes are observed as vertical gradients in radar observables.

Improvement of Fourier Polarimetry for applications in tomographic photoelasticity [PDF]

, 2006
The use of the Fourier Polarimetry method has been demonstrated to extract the three characteristic parameters in integrated photoelasticity. In contrast to the phase-stepping method, it has been shown that the Fourier method is more accurate.
