Polarimetric imaging of biological tissues based on the indices of polarimetric purity [PDF]

Journal of Biophotonics, 2017
We highlight the interest of using the indices of polarimetric purity (IPPs) to the inspection of biological tissues. The IPPs were recently proposed in the literature and they result in a further synthetization of the depolarizing properties of samples.

Performance of Reduced Polarimetric Optical Switching Demodulation Technique in Different Spatio-Temporal Polarization Modulation Schemes

Universe
The beam exchange is a classical supplementary technique for spatio-temporal modulation in a dual-beam setup. In order to save time, the reduced polarimetric-optical-switching (RPOS) technique was propsed as an alternative technique.

Achromatizing a liquid-crystal spectropolarimeter: Retardance vs Stokes-based calibration of HiVIS

, 2010
Astronomical spectropolarimeters can be subject to many sources of systematic error which limit the precision and accuracy of the instrument. We present a calibration method for observing high-resolution polarized spectra using chromatic liquid-crystal ...

Polarimetry microlensing of close-in planetary systems

, 2017
A close-in giant planetary (CGP) system has a net polarization signal whose value varies depending on the orbital phase of the planet. This polarization signal is either caused by the stellar occultation or by reflected starlight from the surface of 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 ...
