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 ...

Jones matrix for image-rotation prisms

Applied Optics, 2004
The polarization-transforming properties of rotational prisms are analyzed with polarized light by using the Jones calculus and the exact ray-trace. A general expression of the Jones matrix for a rotational prism is derived, incorporating an explicit dependence on the image-rotation angle or the wave-front-rotation angle.

Decomposing the images of the Jones matrix microscope for quantitative analysis

Journal of the Optical Society of America A
The polarization of light is a fundamental property, and its measurement is desired for extracting the optical response of the interacting matter. The Jones matrix description directly assesses a sample’s response to the light–matter interactions. The Jones matrix approach uses a coherent basis and is suitable for expressing the interaction of coherent

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.

Self-referenced polarization augmented Jones matrix imaging using cyclic shearing interferometry

Optics Letters
Jones matrices are imperative in polarization holography, elucidating the polarization-dependent anisotropic characterization of birefringent materials. Jones matrices are experimentally measured from complex electric-field components of polarized light and require intricate imaging systems, thereby limiting their adaptability to multidisciplinary ...

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.

Multi-contrast imaging of human posterior eye by Jones matrix optical coherence tomography

SPIE Proceedings, 2017
A multi-contrast imaging of pathologic posterior eyes is demonstrated by Jones matrix optical coherence tomography (Jones matrix OCT). The Jones matrix OCT provides five tomographies, which includes scattering, local attenuation, birefringence, polarization uniformity, and optical coherence angiography, by a single scan.

Polarization-sensitive complex Fourier domain optical coherence tomography for Jones matrix imaging of biological samples

Applied Physics Letters, 2004
A polarization-sensitive Fourier domain optical coherence tomography (PS-FD-OCT) system is demonstrated. This OCT system is based on a spectral interferometer, does not require mechanical axial scanning, and enables phase information to be used in an OCT image.

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.
