Spatial frequency domain Mueller matrix imaging. [PDF]

J Biomed Opt, 2022
Mueller matrix polarimetry (MMP) and spatial frequency domain imaging (SFDI) are wide-field optical imaging modalities that differentiate tissue primarily by structure alignment and photon transport coefficient, respectively. Because these effects can be related, combining MMP and SFDI may enhance tissue differentiation beyond the capability of each ...

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.

Detection and Discrimination of Bacterial Colonies with Mueller Matrix Imaging. [PDF]

Sci Rep, 2018
AbstractThe polarization imaging technique is a powerful approach to probe microstructural and optical information of biological structures (e.g., tissue samples). Here, we have studied the polarization properties of different bacterial colonies in order to evaluate the possibility of bacterial detection and discrimination.

Mueller Matrix Imaging Optimized by Uniform Illumination

Frontiers in Physics, 2022
In this study, we present a flat-field Mueller matrix imaging system to reduce the reconstruction error caused by critical illumination. This study demonstrates that the signal-to-noise ratio (SNR) of the reconstructed images is improved by about eight ...

Ultra-wide-field imaging Mueller matrix spectroscopic ellipsometry for semiconductor metrology [PDF]

Nature Communications
We propose an ultra-wide-field imaging Mueller matrix spectroscopic ellipsometry (IMMSE) system for semiconductor metrology. The IMMSE system achieves large-area measurements with a 20 mm × 20 mm field of view (FOV)—the largest FOV reported to date—and a

Nanoform evaluation approach using Mueller matrix microscopy and machine learning concepts [PDF]

EPJ Web of Conferences, 2022
We realized an imaging Mueller matrix microscope for nanostructure characterization. For investigations on nanoform characterization via Mueller matrix images, we measured and simulated Mueller matrix images of specially designed nanostructures.
