An application of Mueller matrix polarimetry for characterising properties of thin film with surface roughness

MATEC Web of Conferences, 2015
A new Mueller ellipsometry method was proposed for characterising the optical properties of thin films with rough surfaces. The validity of the proposed study is demonstrated by comparing the experimental results of the refractive index and thickness of ...

Probing intrinsic anisotropies of fluorescence: Mueller matrix approach

, 2015
We demonstrate that information on "intrinsic" anisotropies of fluorescence originating from preferential orientation/organization of fluorophore molecules can be probed using a Mueller matrix of fluorescence.

Visualizing Phase Transition Behavior of Dilute Stimuli Responsive Polymer Solutions via Mueller Matrix Polarimetry

, 2015
Probing volume phase transition behavior of super-diluted polymer solutions both micro- and macroscopically still persist as an outstanding challenge. In this regard, we have explored 4x4 spectral Mueller matrix measurement and its inverse analysis for ...

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

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
