Singular approach to the analysis of Jones matrix images of biological crystals networks

Photonics Applications in Astronomy, Communications, Industry, and High-Energy Physics Experiments 2019, 2019
A theoretical basis for the method of polarization-interference mapping of optically thin polycrystalline films of human biological fluids is given. The coordinate distributions of the value of the local contrast of the interference distributions of the polarization-inhomogeneous microscopic images of polycrystalline films of the synovial fluid of the ...

Methods and devices of laser layer Jones-matrix mapping

International Conference on Correlation Optics
We introduce and experimentally test a polarization–interference Jones-matrix imaging method with layer-by-layer phase scanning on synovial-fluid facies and quantify its diagnostic efficiency. Combining polarization interferometry, digital phase scanning,

Quantitative analysis of samples via Jones matrix

Future Sensing Technologies
Accurate characterization of anisotropy is crucial for understanding the light-matter interaction. Conventional intensity-based imaging often lacks the sensitivity to resolve subtle birefringent features in weakly anisotropic samples.

Real‐Time Jones Matrix Synthesis by Compact Polarization Inline Holographic Microscopy

Laser & Photonics Reviews
The Jones matrix is a powerful quantitative tool for polarimetric imaging and characterization, where the matrix elements represent the intrinsic optical properties of the anisotropic objects on interaction with the polarized light.

Statistical and cross-correlation structure of Jones-matrix images of polycrystalline films of biological fluids

Advanced Topics in Optoelectronics, Microelectronics, and Nanotechnologies IX, 2018
The paper presents the results of Jones-matrix mapping of optically thin, non-depolarizing biological fluids with different polycrystalline structure – bile and cerebrospinal fluid (liquor). The Jones matrix model of manifestations of polarizing mechanisms of phase anisotropy of such layers is presented.

Investigations in Jones matrix polarization-sensitive optical coherence tomography for dermatological imaging and characterization

2023
Optical coherence tomography (OCT) is a non-invasive imaging modality that provides high-resolution, three-dimensional images of biological tissue. Since its introduction in the 1990s, it has gained widespread adoption in ophthalmology, and it has also garnered interest in other clinical applications, such as dentistry, endoscopy, and dermatology.

Multiparameter polarization jones matrix reprography and web design of digital images bibrefriction of printing materials

Optoelectronic Information-Power Technologies
A model-design of the polycrystalline structure of polyethylene films is proposed. Within the framework of reprography, a method of statistical, correlation and fractal analysis of the distributions of characteristic values of graphic Jones matrix images of birefringent polyethylene films has been developed.
