Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose. [PDF]

Adv Mater
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

Snapshot Mueller matrix polarimetry by wavelength polarization coding and application to the study of switching dynamics in a ferroelectric liquid crystal cell.

EPJ Web of Conferences, 2010
This paper describes a snapshot Mueller matrix polarimeter by wavelength polarization coding. This device is aimed at encoding polarization states in the spectral domain through use of a broadband source and high-order retarders.

Mueller coherency matrix method for contrast image in tissue polarimetry [PDF]

SPIE Proceedings, 2007
In this work, we propose the use of the Mueller Coherency matrix of biological tissues in order to increase the information from tissue images and so their contrast. This method involves different Mueller Coherency matrix based parameters, like the eigenvalues analysis, the entropy factor calculation, polarization components crosstalks, linear and ...

Reflection mode polarimetry guides laser mass spectrometry to diagnostically important regions of human breast cancer tissue [PDF]

Scientific Reports
To enhance the clinical utility of mass spectrometry (MS), lengthy dwell times on less informative regions of patient specimens (e.g., adipose tissue in breast) must be minimized. Additionally, a promising variant of MS known as picosecond infrared laser

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Although the distribution of corneal birefringence has been reported, depth resolved MMP imaging of the cornea has not been archived and remains challenging.
