Point Source C-band Mueller Matrices for the Green Bank Telescope

The Astronomical Journal, 2023
C -band Mueller matrices for the Green Bank Telescope are presented here which enable on-sky Stokes parameters for point sources at the beam center to be determined. Standard calibrators, 3C 138 and 3C 286, were observed using the Spider program to steer

On-axis Polarization Calibration of the FAST L-band 19-beam Receiver

The Astronomical Journal
We present the polarization calibration of the 19-beam receiver at 1420 MHz within the full illumination of the Five-hundred-meter Aperture Spherical radio Telescope from 2018 October to 2023 March.

Mueller Matrix Polarimetric Imaging Analysis of Optical Components for the Generation of Cylindrical Vector Beams

Crystals, 2020
In this work, we performed a Mueller matrix imaging analysis of two commercial optical components usually employed to generate and manipulate vector beams—a radial polarizer and a liquid-crystal q-plate.

Mueller matrix interpolation in polarization optics [PDF]

Journal of the Optical Society of America A, 2010
The question of the physical significance of the Mueller matrix average is addressed by means of an analysis of interpolation processes. We draw a comparison between two interpolation processes. The first one is related to the classical Euclidean metrics and the second one is based on the log-Euclidean metrics.

Decomposition and interpretation of Mueller matrices

EPJ Web of Conferences, 2010
The various decompositions of depolarizing Mueller matrices into products of basic optical devices, i.e. retarders, diattenuators and depolarizers, are critically revisited.

On the noise and physical realizability of experimental polarimetric images

EPJ Web of Conferences, 2010
Optical polarimetric images are usually calculated from a set of intensity images recorded with different states of polarization of light [1] . Be cause these latter states are setup dependent, propagation of experimental noise to polarimetric images ...
