Method of Directly Writing MPA on Photosensitive Surface of Detector Based on FIB [PDF]

open access: yesSensors
The division of focal plane (DoFP) polarization detector has great potential for the development of aerospace polarimeters, but the existing commercial DoFP polarization detector cannot satisfy all the missions due to the diversity of satellite payloads.

CMAG: A Mission to Study and Monitor the Inner Corona Magnetic Field

open access: yesAerospace, 2023
Measuring magnetic fields in the inner corona, the interface between the solar chromosphere and outer corona, is of paramount importance if we aim to understand the energetic transformations taking place there, and because it is at the origin of ...

Eigenvalue calibration methods for polarimetry [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2012
Complex polarisation sensitive systems such as imaging Mueller matrix polarimeters are commonly calibrated using the eigenvalue calibration method. In this paper we present an extensive review of the method and an existing variant.

Hadron Polarimetry for the Electron-Ion Collider

open access: yesSciPost Physics Proceedings, 2022
The Electron-Ion Collider (EIC) will be the first collider to use both polarized electron beams and polarized proton and light ion beams. It will therefore offer unique opportunities to study the structure of nucleons and to answer fundamental questions ...

An All-Dielectric Metasurface Polarimeter [PDF]

open access: yesACS Photonics, 2022
We demonstrate an all-dielectric meta-polarimeter with a single unit-cell design capable of direct measurement of any arbitrary polarization states, achieving a polarization-measurement fidelity of 99 ± 1%. This holds promise for ultra-compact polarization imaging and quantum state tomography.
