Systematic simulations of aerosol optical property retrieval uncertainty for scanning polarimeters

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
Scanning polarimeters, which utilize multi-angle, multispectral polarimetric observations from aircraft and orbit, represent the next generation of instruments capable of determining aerosol and cloud properties remotely.

Electro-optical polarimeters for ground-based and space-based observations of the solar K-corona [PDF]

open access: yes, 2012
Polarimeters based on electro-optically tunable liquid crystals (LC) represent a new technology in the field of observational astrophysics. LC-based polarimeters are good candidates for replacing mechanically rotating polarimeters in most ground-based ...

Zero-polarization candidate regions for the calibration of wide-field optical polarimeters [PDF]

open access: yes
Context. The calibration of optical polarimeters relies on the use of stars with negligible polarization (i.e., unpolarized standard stars) for determining the instrumental polarization zero point.

Measurements of the polarization properties of foam materials useful for mm-wave polarimeters windows [PDF]

open access: yes, 2016
We have measured in the W-band, using a custom setup, the absorption and polarization properties in transmission of foam materials (elyfoama"double dagger, styrodura"double dagger, plastazotea"double dagger, and propozotea"double dagger) useful for ...

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

open access: yesEPJ 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.
