Miniaturizing optical coherence tomography
Translational 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.

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 ...

Optical coherency matrix tomography [PDF]
Scientific Reports, 2015 AbstractThe coherence of an optical beam having multiple degrees of freedom (DoFs) is described by a coherency matrixGspanning these DoFs. This optical coherency matrix has not been measured in its entirety to date—even in the simplest case of two binary DoFs whereGis a 4 × 4 matrix.

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 ...

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 ...

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.

Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging [PDF]
, 2014 We report a Talbot bands-based optical coherence tomography (OCT) system capable of producing longitudinal B-scan OCT images and en-face scanning laser ophthalmoscopy (SLO) images of the human retina in-vivo, with various degrees of ...

Panretinal Optical Coherence Tomography
IEEE Transactions on Medical Imaging, 2023 We introduce a new concept of panoramic retinal (panretinal) optical coherence tomography (OCT) imaging system with a 140° field of view (FOV). To achieve this unprecedented FOV, a contact imaging approach was used which enabled faster, more efficient, and quantitative retinal imaging with measurement of axial eye length.

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
