Evaluation of a cheap ultrasonic stage for light source coherence function measurement, optical coherence tomography and dynamic focusing [PDF]

open access: yes, 2009
We evaluate the performance of a cheap ultrasonic stage in setups related to optical coherence tomography. The stage was used in several configurations: (1) optical delay line in an optical coherence tomography (OCT) setup; (2) as a delay line measuring ...

Measurement of angular distributions by use of low-coherence interferometry for light-scattering spectroscopy [PDF]

open access: yes, 2001
We present a novel interferometer for measuring angular distributions of backscattered light. The new system exploits a low-coherence source in a modified Michelson interferometer to provide depth resolution, as in optical coherence tomography, but ...

Miniaturizing optical coherence tomography

open access: yesTranslational Biophotonics, 2022
Optical coherence tomography (OCT) has revolutionized ophthalmic diagnosis as a non‐invasive, cross‐sectional imaging technique in the last 30 years and hence is one of the fastest adopted advanced imaging technologies in the history of medicine.

Inverse scattering problem for optical coherence tomography [PDF]

open access: yes, 2003
We deal with the imaging problem of determining the internal structure of a body from backscattered laser light and low-coherence interferometry. Specifically, using the interference fringes that result when the backscattering of low-coherence light is ...

Arterial macroaneurysm of the optic disc

open access: yesAmerican Journal of Ophthalmology Case Reports, 2018
Purpose: We present fundus and spectral domain optical coherence tomography findings of a patient with an arterial macroaneurysm of the optic disc. Observations: An 87-year-old woman presented with blurry vision and was found to have a retinal arterial ...

Cross-Polarized Optical Coherence Tomography System with Unpolarized Light

open access: yesPhotonics, 2022
Cross-polarized optical coherence tomography offers improved contrast for samples which can alter the polarization of light when it interacts with the sample. This property has been utilized to screen pathological conditions in several organs.

An overview of optical coherence tomography angiography and the posterior pole

open access: yesTherapeutic Advances in Ophthalmology, 2019
Optical coherence tomography angiography is a relatively new, noninvasive technology that has revolutionized imaging of the retinal and choroidal microvasculature. This technology is based on the detection of movement or changes that represent moving red

The Choroid and Optical Coherence Tomography

open access: yesTürk Oftalmoloji Dergisi, 2016
The choroid is the most vascular tissue in the eye and it plays an important role in the pathophysiology of various common chorioretinal diseases such as central serous retinopathy, age-related macular degeneration and degenerative myopia.
