Mueller polarimetry of discontinuous gold films

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2019
The problem of controlling morphology of discontinuous gold films by the method of optical angular Mueller-polarimetry is considered. A set of the samples of such films with different amounts of sputtered metal has been fabricated and studied.

Depth-resolved Mueller matrix polarimetry microscopy of the rat cornea. [PDF]

Biomed Opt Express, 2020
Mueller matrix polarimetry (MMP) is a promising linear imaging modality that can enable visualization and measurement of the polarization properties of the cornea. Although the distribution of corneal birefringence has been reported, depth resolved MMP imaging of the cornea has not been archived and remains challenging.

A Practical Guide to Mueller Matrix Analysis of Chiroptical Materials. [PDF]

Chirality
This study presents a unified theoretical framework and closed‐form Mueller matrix expressions for analyzing chiroptical properties across six fundamental polarization properties that lead to different macroscopic symmetries. We provide an experimental protocol to successfully isolate intrinsic circular dichroism from apparent wavevector‐dependent ...

Full Vectorial Field Sensing Using Liquid Crystal Droplet Arrays. [PDF]

Adv Mater
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

Tuning Circular Dichroism and Circularly Polarised Luminescence in Single Crystals of a Perylene Diimide Macrocycle. [PDF]

Angew Chem Int Ed Engl
The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,

Mueller matrix polarimetry for improved liver fibrosis diagnosis [PDF]

Optics Letters, 2012
An experimental Mueller matrix polarimeter is used to quantify human liver fibrosis by measuring retardance and depolarization of thin biopsies. The former parameter is sensitive to fibrillar collagen, the latter is specifically sensitive to fibrillar collagen around blood vessels, which is not significant for liver fibrosis diagnosis.
