Dual-Angle Mueller Matrix Polarimetry for Single Cell

IEEE Sensors Journal
Label-free single-cell analysis plays a crucial role in the biomedical field. In this article, we propose a dual-angle Mueller matrix polarimetry (DMMP) measurement system for the label-free classification and characterization of single cells.

Stokes-Mueller matrix polarimetry system for glucose sensing

Optics and Lasers in Engineering, 2017
Abstract A Stokes-Mueller matrix polarimetry system consisting of a polarization scanning generator (PSG) and a high-accuracy Stokes polarimeter is used to sense the glucose concentration in aqueous solutions with and without scattering effects, respectively.

Fast complete Mueller matrix polarimetry microscopy using a single polarization camera

Optics and lasers in engineering
We propose a fast microscopic polarimeter for complete Mueller matrix imaging by using two rotating retarders and one polarization camera. Our new design allows us to compute the full Mueller matrix by 6 measurements in only ∼1.4s.

Model for the depolarizing retarder in Mueller matrix polarimetry

Journal of the Optical Society of America A, 2022
We advance an analytical model describing the polarimetric response of a depolarizing retarder whose retardance varies spatially in magnitude or in orientation. The variation of the retarder parameters may be either of deterministic or of random nature. The model provides both the mean values and the uncertainties of the parameters.

Determination of Mueller Matrix for Metal Substrates by Stokes Polarimetry

IEEE Transactions on Instrumentation and Measurement, 2021
This article focuses on a polarization measurement method based on Mueller calculus for determining the polarization properties of metal substrates. As the Mueller matrix of a medium provides all its polarization-altering properties, the presented method enables to predict the effect of any optically absorbing media on the polarization state of light ...

Recognition of microplastics suspended in seawater via refractive index by Mueller matrix polarimetry.

Marine Pollution Bulletin, 2023
Microplastics have become the marine pollution posing a human health risk, but they are difficult to be detected and recognized for different materials, irregular shapes, and broad size distributions.

Channeled partial Mueller matrix polarimetry

SPIE Proceedings, 2015
In prior work,1,2 we introduced methods to treat channeled systems in a way that is similar to Data Reduction Method (DRM), by focusing attention on the Fourier content of the measurement conditions. Introduction of Q enabled us to more readily extract the performance of the system and thereby optimize it to obtain reconstruction with the least noise ...

Terahertz Mueller Matrix Polarimetry and Polar Decomposition

IEEE Transactions on Terahertz Science and Technology, 2020
Mueller matrix imaging, as one of the polarimetric imaging modalities, is an effective tool to achieve imaging enhancement as well as explore fine details of the imaged sample at microwave and optical frequencies. However, little work has been reported at terahertz (THz) frequencies, which could provide an exclusive insight in exploring fine details of
