Visualisation methods for polarimetric imaging

, 2021
Polarimetric imaging is a technique for measuring the spatial correlations of the aspects of the polarisation of light. Since human vision is essentially unable to detect polarisation, the data obtained from this imaging technique must be converted into the channels of the human visual system in order to visually process the spatial correlations in the

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics

Laser &Photonics Reviews, EarlyView.
ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...
