Compton Polarimetry

, 2022
Photons preferentially Compton scatter perpendicular to the plane of polarisation. This property can be exploited to design instruments to measure the linear polarisation of hard X-rays ($\sim$10 - 100 keV). Photons may undergo two interactions in the sensitive volume of the instrument, i.e. a scattering followed by an absorption.

The Polarizability Vector: A Polarimetric Observable for Characterizing Anisotropic Nanoparticles

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
We find an overlooked observable in Nanophotonics that characterizes the optical response of anisotropic nanoparticles from simple polarimetry measurements. ABSTRACT The optical properties of anisotropic nanoparticles (NPs) are often characterized by two principal components of their polarizability tensor.

Polarimeters for the Detection of Anisotropy from Reflectance

Micromachines
Polarimetry is used to determine the Stokes parameters of a laser beam. Once all four S0,1,2,3 parameters are determined, the state of polarisation is established.

Preservation of Historically and Scientifically Important Geospatial Data From Venus

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Gamma-ray polarimetry [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003
An astrophysics application of a low noise Double-sided Silicon Strip Detector (DSSD) is described. A Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gamma-ray universe in the 0.1-20 MeV energy band. Excellent energy resolution and polarization sensitivity are key features of the SMCT.
