Probing Dynamic Variation of Layered Microstructure Using Backscattering Polarization Imaging

open access: yesPhotonics, 2022
Polarization imaging can quantitatively probe the microscopic structure of biological tissues which can be complex and consist of layered structures. In this paper, we established a fast-backscattering Mueller matrix imaging system to characterize the ...

On the algebraic characterization of a Mueller matrix in polarization optics - I. Identifying a mueller matrix from its N matrix [PDF]

open access: yes, 1998
We revisit the problem of identifying a Mueller matrix M through its N matrix N = (M) over tilde GM where G is the familiar Minkowski matrix diag (1, -1, -1, -1) and the tilde denotes matrix transposition.

The effect of relative humidity on the polarization Mueller matrix under the oil smoke environment

open access: yesFrontiers in Physics, 2023
For the variation of the polarized Mueller matrix of oil smoke particles under different relative humidity levels, the polarized single scattering characteristics of oil smoke particles are studied by using the Mie scattering theory, and the multiple ...
