Stress Detection of Conical Frustum Windows in Submersibles Based on Polarization Imaging

Sensors, 2022
Stress detection of the conical frustum window is a very important issue to ensure the safety of deep manned submersibles. In this paper, we propose a method based on polarization imaging to evaluate the stress accumulation and recovery in the conical ...

Mueller matrix imaging polarimetry technique for dengue fever detection

Optics Communications, 2022
Abstract Dengue fever is one of the most common diseases in tropical and sub-tropical regions of the world, and has a variety of unpleasant and painful symptoms, including fever, bleeding, and even death. Thus, effective methods for its early-stage detection and diagnosis are urgently required.

Structure‐Response Relationships in Rigid C2‐Symmetric Excitonic Systems: Principles, Modulation, and Functional Design Strategies

ChemPhysChem, Volume 27, Issue 2, January 2026.
Rigid C2‐symmetric chromophores reveal how transition dipole orientation, magnitude, and conformational locking govern exciton coupling and g‐factor amplification, providing a structural blueprint for the rational design of advanced chiroptical molecular and material architectures.

Arbitrary polarization control with a segmented APPLE‐II undulator

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 73-83, January 2026.
A four‐segmented APPLE‐II undulator was constructed, and its operation has started at NanoTerasu BL13U. The performance of arbitrary polarization control using phase shifters is demonstrated.A newly developed four‐segmented APPLE‐II undulator enables arbitrary polarization control in the soft to tender X‐ray region.

Compound meta‐optics: there is plenty of room at the top

Nanophotonics, Volume 14, Issue 23, Page 3835-3849, 02 November 2025.
Abstract Metasurfaces have been widely exploited in imaging and sensing, holography, light–matter interaction, and optical communications in free space and on chip, thanks to their CMOS compatibility, versatility and compact form. However, as this technology matured from novelty to performance, stringent requirements on diffraction efficiency ...

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

Advanced Functional Materials, Volume 35, Issue 45, November 5, 2025.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

QUANTITATIVE MUELLER MATRIX POLARIMETRY TECHNIQUES FOR BIOLOGICAL TISSUES

Journal of Innovative Optical Health Sciences, 2012
We propose and conduct both the rotating linear polarization imaging (RLPI) and Mueller matrix transformation (MMT) measurements of different biological tissue samples, and testify the capability of the Mueller matrix polarimetry for the anisotropic scattering media.
