Demonstration of Compact In situ Mueller-Matrix Polarimetry Based on Binary Polarization Rotators

open access: yesIEEE Access, 2019
We develop a compact in situ Mueller-matrix polarimetry (MMP) based on binary polarization rotators for on-machine optical processing measurements. The presented in situ MMP could measure the polarization properties of free-space reflective samples by ...

Light‐Imprinted Chirality in Nanomaterials: From Principles to Applications

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
Light‐induced chirality represents a transformative paradigm for fabricating chiral nanostructures. This review provides a comprehensive framework encompassing light‐based strategies for imprinting and tuning chirality in nanomaterials, which guides researchers in harnessing light to create next‐generation functional materials.

Chiral Phase Change Nanomaterials

open access: yesAdvanced Functional Materials, Volume 36, Issue 67, 20 August 2026.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Helically Flexible Boron‐Dipyrromethenes for Solution‐Processed Isotropic Films With Preserved Chiral Exciton Coupling

open access: yesAggregate, Volume 7, Issue 8, August 2026.
Accessible and chiroptically tunable helically chiral boron‐dipyrromethene dimer dyes enable the fabrication of solution‐processed isotropic neat thin films that retain sharp visible electronic circular dichroism signatures from solution. This platform establishes a direct molecule‐to‐material relationship and provides a robust foundation for the ...

Metasurface-enabled compact, single-shot and complete Mueller matrix imaging

open access: yes, 2023
When light scatters off an object its polarization, in general, changes - a transformation described by the object's Mueller matrix. Mueller matrix imaging polarimetry is an important technique in science and technology to image the spatially varying ...

The Combination of Chiral Assembly and Chiral Template Effects Boosts Circularly Polarized Luminescence of Perovskite Nanocrystals

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
We show that the hierarchical order of perovskite nanocrystal assemblies formed within a nanostructured, chal liquid‐crystalline template exhibits extremely high circularly polarized luminescence (CPL). This is due to the helical arrangement of PNCs in the template voids and capitalizes on the inherent electrooptic properties of the template ...

Polarized Light Microscopy for Quantitative Assessment of Sarcomere‐Scale Structural Order in Cardiac Tissue

open access: yesJournal of Biophotonics, Volume 19, Issue 8, August 2026.
Impact of cardiac and respiratory arrest on cardiac muscle tissue. Wistar rats were injected (on the left) either with cisatracurium to induce a respiratory arrest or lidocaine to induce a cardiac arrest (in the middle). Further, the pathophysiological changes developed and were assessed with linear polarization microscopy at 600–3000 nm wavelength ...

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

open access: yesSensors, 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 polarimetry for differentiating characteristic features of cancerous tissues

open access: yesJournal of Biomedical Optics, 2014
Polarization measurements allow one to enhance the imaging contrast of superficial tissues and obtain new polarization sensitive parameters for better descriptions of the micro- and macro- structural and optical properties of complex tissues. Since the majority of cancers originate in the epithelial layer, probing the morphological and pathological ...
