Investigation on the potential of Mueller matrix imaging for digital staining

Journal of Biophotonics, 2015
Digital staining based on Mueller matrix measurements and their derivatives was investigated. Mueller matrix imaging was performed at the microscopic level on gastric tissue sections. Full Mueller matrices (4 × 4) were reconstructed using recorded images, followed by the extraction of polarization parameters.

Structured illumination Mueller matrix imaging. [PDF]

Biomed Opt Express, 2019
We perform Mueller matrix imaging (MMI) of diffusely scattering phantoms under sinusoidal irradiance of varying spatial frequency. Quantitative polarimetric sensing via MMI completely characterizes a sample's polarimetric properties, while structured illumination (SI) allows for the control of photon path length.

Mueller Matrix Ellipsometric Approach on the Imaging of Sub-Wavelength Nanostructures

Frontiers in Physics, 2022
Conventional spectroscopic ellipsometry is a powerful tool in optical metrology. However, when it comes to the characterization of non-periodic nanostructures or structured fields that are much smaller than the illumination spot size, it is not well ...
