We present a general theory of spin-to-orbital angular momentum (AM) conversion of light in
focusing, scattering, and imaging optical systems. Our theory employs universal geometric …

We show, both theoretically and experimentally, that high-numerical-aperture (NA) optical
microscopy is accompanied by strong spin-orbit interaction of light, which translates fine …

We show that, in order to attain complete polarization control across a beam, two spatially
resolved variable retardations need to be introduced to the light beam. The orientation of the …

A spherical nanoparticle can scatter tightly focused optical beams in a spin-segmented
manner, meaning that the far field of the scattered light exhibits laterally separated left-and …

We report on the development of super-resolution polarization (parameter) indirect
microscopic imaging (PIMI) and its application to visualizing and quantifying graphene …

Polarization imaging finds applications in many areas, such as photoelasticity, ellipsometry,
and biomedical imaging. A compact, snapshot, and high-efficiency imaging polarimeter is …

We present the analysis and implementation of a set of experimental procedures to
characterize optical polarization properties as a function of the applied voltage for liquid …

The calibration of the polarization effect of a high-numerical-aperture (high-NA) objective
lens (OL) is of great significance for high-precision polarized light micro-imaging. In this …

A method for using liquid-crystal variable retarders (LCVRs) with continually varying voltage
to measure the complete Mueller matrix of a general sample is presented. The LCVRs are …

We present a method for using liquid-crystal variable retarders (LCVR's) with continually
varying voltage to measure the Stokes vector of a light beam. The LCVR's are usually …
