Imaging polarimetry in the LWIR with microgrid polarimeters
EPJ Web of Conferences, 2010 Microgrid polarimeters have emerged over the past decade as a viable tool for performing real-time, highly accurate polarimetric imagery. A microgrid polarimeter operates by integrating a focal plane array (FPA) with an array of micropolarizing optics.

Searching for Axion-Like Particles with X-ray Polarimeters
Galaxies, 2018 X-ray telescopes are an exceptional tool for searching for new fundamental physics. In particular, X-ray observations have already placed world-leading bounds on the interaction between photons and axion-like particles (ALPs).

Calibration System with Cryogenically-Cooled Loads for CMB Polarization Detectors
, 2011 We present a novel system to calibrate millimeter-wave polarimeters for CMB polarization measurements. This technique is an extension of the conventional metal mirror rotation approach, however it employs cryogenically-cooled blackbody absorbers.

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging
Nanophotonics, Volume 15, Issue 9, 13 May 2026.This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.
