Fibre optic fizeau intererometer for optical coherence tomography [PDF]

, 2006
The aim of the project was to develop the Fizeau interferometer configuration to take advantage of the benefits derived from its “downlead insensitivity” to temperature and polarisation fading.

Tissue surface as the reference arm in Fourier domain optical coherence tomography [PDF]

, 2012
We present a simple method applicable to common-path Fourier domain optical coherence tomography (OCT) in which the tissue surface is used as the reference arm.

Optical coherence tomography and optical coherence tomography angiography in multiple sclerosis

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2023
Background In multiple sclerosis (MS), optical coherence tomography (OCT) has become a sensitive tool for evaluating retinal and optic nerve diseases. Optical coherence tomography angiography (OCT-A) is a novel technique that can assess the density of ...

Optical Coherence Tomography [PDF]

Science, 1991
A technique called optical coherence tomography (OCT) has been developed for noninvasive cross-sectional imaging in biological systems. OCT uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way that is analogous to ultrasonic pulse-echo imaging.

Cross-Polarization Optical Coherence Tomography for Brain Tumor Imaging

Frontiers in Oncology, 2019
This paper considers valuable visual assessment criteria for distinguishing between tumorous and non-tumorous tissues, intraoperatively, using cross-polarization OCT (CP OCT)—OCT with a functional extension, that enables detection of the polarization ...

Phantoms for performance assessment of optical coherence tomography systems [PDF]

, 2012
In this paper, we describe the procedures to make epoxy resin and agarose phantoms designed using Mie scattering calculations. The phantoms are constructed to be used in the estimation of point spread function (PSF) of an optical coherence tomography ...
