Miniaturizing optical coherence tomography

Translational Biophotonics, 2022
AbstractOptical 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.

Nano-optic endoscope for high-resolution optical coherence tomography in vivo

Nature Photonics, 2018
Acquisition of high-resolution images from within internal organs using endoscopic optical imaging has numerous clinical applications. However, difficulties associated with optical aberrations and the trade-off between transverse resolution and depth of ...

Optical coherence tomography angiography in preclinical Alzheimer’s disease

British Journal of Ophthalmology, 2019
Background/aims As a protrusion from the brain, the retina might reflect the status of the brain. Previous studies showed a decrease in vessel density and foveal avascular zone (FAZ) enlargement on optical coherence tomography angiography (OCTA) in ...

Inverse scattering problem for optical coherence tomography [PDF]

, 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 ...

Optical Coherence Tomography of Cholesteatoma [PDF]

Otology & Neurotology, 2010
To image cholesteatoma using optical coherence tomography (OCT) and correlate the results with clinical findings and conventional observations obtained using binocular microscopy and histology. OCT is a high-resolution optical imaging modality that generates cross-sectional images of turbid media, such as tissue with resolution approaching that of ...

Optical coherence tomography

Journal of Biomedical Optics, 1996
This paper gives an introduction to optical coherence tomography (OCT), explains its basic principles, and discusses the information content of OCT images. Various interferometric techniques used in OCT are reviewed and a short survey of results obtained so far in different fields of application and possible future developments are presented.

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 ...
