Physical Significance of the Determinant of a Mueller Matrix

Photonics, 2022
The determinant of a Mueller matrix M plays an important role in both polarization algebra and the interpretation of polarimetric measurements. While certain physical quantities encoded in M admit a direct interpretation, the understanding of the ...

Sensing birefringence and diattenuation with undetected light

Optics Express
Developing advanced technologies for sensing and imaging biological samples is crucial for medical applications, making quantum-enhanced methods particularly valuable, as they promise significant benefits over classical techniques. An important aspect of biological imaging is the characterization of tissue, which often involves resolving complex ...

Pupil Plane Multiplexing for Vectorial Fourier Ptychography

Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

Improved cloud-phase determination of low-level liquid and mixed-phase clouds by enhanced polarimetric lidar [PDF]

Atmospheric Measurement Techniques, 2018
The unambiguous retrieval of cloud phase from polarimetric lidar observations is dependent on the assumption that only cloud scattering processes affect polarization measurements.

Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

Fourier ptychography microscopy for digital pathology

Journal of Microscopy, Volume 300, Issue 2, Page 260-285, November 2025.
Abstract Fourier ptychography microscopy (FPM) has made significant progress since its invention in 2013, thanks to its adaptable nature, high resolution, and vast field‐of‐view capabilities. FPM is used in various medical applications across multiple optical wavelengths, from automated digital pathology to radiology and ultraviolet label‐free imaging.

High Precision Stokes Polarimetry for Scattering Light using Wide Dynamic Range Intensity Detector

MATEC Web of Conferences, 2015
This paper proposes a Stokes polarimetry for scattering light from a sample surface. To achieve a high accuracy measurement two approaches of an intensity detector and analysis algorism of a Stokes parameter were proposed.

Enhanced Circularly Polarized Lasing in Nanocellulose‐Silica Composites

Advanced Optical Materials, Volume 13, Issue 17, June 17, 2025.
This study demonstrates enhanced circularly polarized lasing emission using cholesteric crystalline nanocellulose (CNC) films embedded with silica nanospheres. The addition of silica spheres significantly boosts circular dichroism by suppressing linear diattenuation, improving the circular polarization.
