Observation of Target Electron Momentum Effects in Single-Arm M\o ller Polarimetry

, 1994
In 1992, L.G. Levchuk noted that the asymmetries measured in M\o ller scattering polarimeters could be significantly affected by the intrinsic momenta of the target electrons.

Error analysis of single-snapshot full-Stokes division-of-aperture imaging polarimeters.

Optics Express, 2015
Single-snapshot full-Stokes imaging polarimetry is a powerful tool for the acquisition of the spatial polarization information in real time. According to the general linear model of a polarimeter, to recover full Stokes parameters at least four ...

Chip-scale, full-Stokes polarimeter

Optics Express, 2019
The polarization of light conveys unique information that can be exploited by crucial applications. The bulky and costly discrete optical components used in conventional polarimeters limit their broad adoption. A compact, low-cost polarimeter would bring this functionality into a myriad of new scenarios and revolutionize its exploitation.
