Mueller Matrix Associated with an Arbitrary 4×4 Real Matrix. The Effective Component of a Mueller Matrix

Photonics
Due to the limited accuracy of experimental data, Mueller polarimetry can produce real 4×4 matrices that fail to meet required covariance or passivity conditions.

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

Aggregate, 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 ...

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 ...

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

Angewandte 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 ...

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 ...

Optimizing Mueller polarimetry in noisy systems through over-determination

Applied Optics, 2021
Mueller polarimetry measurements are increasingly being used to image highly dynamic and short-lived phenomena such as plasma discharges. For phenomena such as these, exposure times below 1 µs must be used. Unfortunately, these low exposure times significantly reduce the signal-to-noise ratio, making accurate and consistent ...

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

Thermodynamic Reversibility in Polarimetry

Photonics, 2022
The action of linear media on incident polarized electromagnetic waves can produce two kinds of thermodynamic irreversible effects, namely, loss of intensity, in general anisotropic, and reduction of the degree of polarization. Even though both phenomena

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.
