We present a precise, portable, and inexpensiveMueller matrix polarimeter based on a pair of twisted nematic liquid crystal plates. Such a design is of interest to low-budget users or to those who require a portable ...

In this work, the error sources that affect a dual rotating retarder polarimeter working in a discrete rotation scheme are studied. Moreover, those errors not sufficiently analyzed in the literature are addressed in detail. ...

We report a measurement of the power spectrum of cosmic microwave background (CMB) lensing from two seasons of Atacama Cosmology Telescope polarimeter (ACTPol) CMB data. The CMB lensing power spectrum is extracted from ...

In this paper we present the analysis, optimization and implementation of several Stokes polarimeter configurations based on a setup including two variable retarders. The polarimeter analysis is based on the Mueller-Stokes ...

Recently, we introduced the basic concepts behind a new polarimeter device based on conical refraction (CR), which presents several appealing features compared to standard polarimeters. To name some of them, CR polarimeters ...

A synchronous polarimeter was set up for the measurement of small rotation angles of the polarization plane of light. The polarimeter is based on a polarizer–Faraday modulator–analyzer structure with a synchronous detection ...

Context. Scattering polarization in the Sr I 4607.3 Å line observed with high resolution is an important diagnostic of the Sun's atmosphere and magnetism at small spatial scales. Investigating the scattering polarization ...
