Non-destructive characterization of adult zebrafish models using Jones matrix optical coherence tomography. [PDF]

Biomed Opt Express, 2022
The zebrafish is a valuable vertebrate animal model in pre-clinical cancer research. A Jones matrix optical coherence tomography (JM-OCT) prototype operating at 1310 nm and an intensity-based spectral-domain OCT setup at 840 nm were utilized to ...

Computational refocusing of Jones matrix polarization-sensitive optical coherence tomography and investigation of defocus-induced polarization artifacts. [PDF]

Biomed Opt Express, 2022
Here we demonstrate a long-depth-of-focus imaging method using polarization sensitive optical coherence tomography (PS-OCT). This method involves a combination of Fresnel-diffraction-model-based phase sensitive computational refocusing and Jones-matrix ...

Diatomic Metasurface for Efficient Six‐Channel Modulation of Jones Matrix

Laser and Photonics Reviews, 2023
Multi‐channel modulation of Jones matrix facilitates encoding a variety of different functions in metasurfaces. However, multiple channels are usually accompanied by a high system complexity and a low efficiency.

Polarization-Interference Jones Matrix Sensors of Layer-by-Layer Scanning of Polycrystalline Dehydrated Blood Films. Fundamental and Applied Aspects [PDF]

Sensors
To date, visual analysis is mainly used to evaluate images of dehydrated films (facies) of biological fluids—microscopy at various magnifications, illumination with white or polarized light, as well as using a dark field.

Three-dimensional multi-contrast imaging of in vivo human skin by Jones matrix optical coherence tomography. [PDF]

Biomed Opt Express, 2017
A custom made dermatological Jones matrix optical coherence tomography (JM-OCT) is presented. It uses a passive-polarization-delay component based swept-source JM-OCT configuration, but is specially designed for in vivo human skin measurement. The center

Parallel detection of Jones-matrix elements in polarization-sensitive optical coherence tomography. [PDF]

Biomed Opt Express, 2019
The polarization properties of a sample can be characterized using a Jones matrix. To measure the Jones matrix without assumptions of the sample, two different incident states of polarization are usually used.

Jones matrix‐based speckle‐decorrelation angiography using polarization‐sensitive optical coherence tomography

Journal of Biophotonics, 2020
We show that polarization‐sensitive optical coherence tomography angiography (PS‐OCTA) based on full Jones matrix assessment of speckle decorrelation offers improved contrast and depth of vessel imaging over conventional OCTA.
