Jones matrix imaging for transparent and anisotropic sample

SPIE Proceedings, 2015
We propose an experimental technique for two dimensional Jones matrix imaging of transparent and anisotropic sample using polarization interferometer. Employing this technique, the Jones matrix components are measured for polarizer and quarter wave plate and results are compared with theoretical results of the samples.

Imaging of Retinal Disease by Clinical Jones-Matrix Optical Coherence Tomography

Biophotonics Congress: Biomedical Optics 2020 (Translational, Microscopy, OCT, OTS, BRAIN), 2020
Additional biomarkers using OCT will extend applications in clinical ophthalmology. The clinical Jones-matrix OCT (JM-OCT) has been applied for several cases of retinal disease. Extended imaging functions by JM-OCT provide status of tissues.

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.

Jones Matrix Imaging of Biological Samples Using Parallel-Detecting Polarization-Sensitive Fourier Domain Optical Coherence Tomography

Optical Review, 2005
A polarization-sensitive Fourier domain optical coherence tomography (PS-FD-OCT) system has been developed. By using a two-dimensional CCD camera, this PS-FD-OCT simultaneously obtains two spectral interferograms corresponding to orthogonal polarization components of a probing beam. FD-OCT avoids axial mechanical scanning, therefore, two OCT images are

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.

Quantitative Imaging of Tissue Polarization Property by Jones Matrix Optical Coherence Tomography

CLEO: 2015, 2015
A quantitative polarization sensitive optical coherence tomography (PS-OCT), so called Jones matrix (JM-) OCT is presented. This system measures the Jones matrix tomography of biological and medical samples. Jones matrix based signal processing and numerical estimator algorithm are then applied to obtain truly quantitative value of tissue birefringence.
