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

IEEE 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 ...

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

Journal 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 ...

Full Vectorial Field Sensing Using Liquid Crystal Droplet Arrays

Advanced Materials, Volume 38, Issue 39, 13 July 2026.
An inkjet‐printed liquid crystal droplet array enables compact, low‐cost, single‐shot sensing of the full vectorial light field. Within a single platform, it simultaneously retrieves intensity, polarization, and phase, while dual‐wavelength operation highlights its capability for multi‐wavelength optical field characterization. ABSTRACT Determining the

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 ...

Giant Chiroptical Properties in Thin Films of a Chiral Indaceno[1,2‐b:5,6‐b′]Dithiophene‐Based Organic Dye

Aggregate, Volume 7, Issue 7, July 2026.
A new chiral indaceno[1,2‐b:5,6‐b′]dithiophene bis‐thiophenylpropynone (IDT‐TPO) dye, which exhibits giant chiroptical properties (up to 18,000 mdeg) in drop‐casted and spin‐coated thin films upon simple aging, was deeply investigated by means of computational, microscopy, and spatially resolved chiroptical techniques.

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...
