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

Optics Express, 2006 Noninvasive angiography is demonstrated for the in vivo human eye. Three-dimensional flow imaging has been performed with high-speed spectral-domain optical coherence tomography. Sample motion is compensated by two algorithms. Axial motion between adjacent A-lines within one OCT image is compensated by the Doppler shift due to bulk sample motion. Axial

An overview of optical coherence tomography angiography and the posterior pole
Therapeutic 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

Arterial macroaneurysm of the optic disc
American 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 ...

Applications and future directions for optical coherence tomography in dermatology *
British Journal of Dermatology, 2020 Optical coherence tomography (OCT) is a noninvasive optical imaging method that can generate high‐resolution en face and cross‐sectional images of the skin in vivo to a maximum depth of 2 mm.

Dynamic full-field optical coherence tomography: 3D live-imaging of retinal organoids [PDF]
Light: Science & Applications, 2019 Optical coherence tomography offers astounding opportunities to image the complex structure of living tissue but lacks functional information. We present dynamic full-field optical coherence tomography as a technique to noninvasively image living human ...

The Choroid and Optical Coherence Tomography
Türk 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.

Comparing six cases of external macular holes and literature review [PDF]
Revista Brasileira de Oftalmologia, 2023 The characteristic optical coherence tomography finding in solar maculopathy is a well-defined outer retinal hyporeflective space primarily involving the photoreceptor inner and outer segment layers. This typical optical coherence tomography image may be

Optical Coherence Tomography Angiography in Glaucoma
Journal of glaucoma, 2020 Optical coherence tomography angiography (OCTA) is a relatively new, noninvasive, dye-free imaging modality that provides a qualitative and quantitative assessment of the vasculature in the retina and optic nerve head.

Phase-dispersion optical tomography [PDF]
, 2001 We report on phase-dispersion optical tomography, a new imaging technique based on phase measurements using low-coherence interferometry. The technique simultaneously probes the target with fundamental and second-harmonic light and interferometrically ...
