Optical Coherence Tomography [PDF]

open access: yesScience, 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.

Optical coherence tomography angiography

open access: yesProgress in Retinal and Eye Research, 2017
Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that ...

Optical coherence tomography and optical coherence tomography angiography in systemic disease [PDF]

open access: yesTaiwan Journal of Ophthalmology
Optical coherence tomography (OCT) is an integral component of present-day ophthalmologic practice. As use of OCT has increased in popularity and frequency of use, a growing number of systemic diseases are now known to have associated findings on both ...

Optical coherence tomography angiography

open access: yesKerala Journal of Ophthalmology, 2016
Optical coherence tomography angiography (OCTA) is a non-invasive angiography type without a contrast agent, which provides a detailed assessment of the retinal and choroidal vasculature and visualization of blood flow by detecting motions of ...

Optical coherence viscometry [PDF]

open access: yesApplied Physics Letters, 2021
We report a technique, named optical coherence viscometry (OCV), to measure the viscosity of Newtonian fluids in a noncontact manner. According to linear wave theory with small amplitudes, capillary waves are associated with fluid mechanical properties.

Measurement of optical coherence structures of random optical fields using generalized Arago spot experiment

open access: yesOpto-Electronic Science, 2023
The optical coherence structures of random optical fields can determine beam propagation behavior, light–matter interactions, etc. Their performance makes a light beam robust against turbulence, scattering, and distortion.
