Instantaneous complex conjugate resolved spectral domain and swept-source OCT using 3x3 fiber couplers [PDF]

open access: yes, 2005
We report that the complex conjugate artifact in Fourier domain optical coherence tomography approaches (including spectral domain and swept source OCT) may be resolved by the use of novel interferometer designs based on 3x3 and higher order fiber ...

Macular Optical Coherence Tomography Imaging in Glaucoma

open access: yesJournal of Ophthalmic & Vision Research, 2021
The advent of spectral-domain optical coherence tomography has played a transformative role in posterior segment imaging of the eye. Traditionally, images of the optic nerve head and the peripapillary area have been used to evaluate the structural ...

Investigation of retinal morphology alterations using spectral domain optical coherence tomography in a mouse model of retinal branch and central retinal vein occlusion. [PDF]

open access: yesPLoS ONE, 2015
Retinal vein occlusion is a leading cause of visual impairment. Experimental models of this condition based on laser photocoagulation of retinal veins have been described and extensively exploited in mammals and larger rodents such as the rat.

Detection of glaucomatous optic neuropathy with spectral-domain optical coherence tomography: a retrospective training and validation deep-learning analysis.

open access: yesThe Lancet Digital Health, 2019
BACKGROUND Spectral-domain optical coherence tomography (SDOCT) can be used to detect glaucomatous optic neuropathy, but human expertise in interpretation of SDOCT is limited. We aimed to develop and validate a three-dimensional (3D) deep-learning system

Polarization-sensitive spectral-domain optical coherence tomography using a single line scan camera [PDF]

open access: yes, 2007
Polarization-sensitive optical coherence tomography can be used to measure the birefringence of biological tissue such as the human retina. Previous measurements with a time-domain polarization-sensitive optical coherence tomography system revealed that ...

Pixel-Reassigned Spectral-Domain Optical Coherence Tomography

open access: yesIEEE Photonics Journal, 2018
A novel method of pixel reassignment (PRA) is proposed to achieve transverse superresolution in the confocal microscopy. Inspired by it, for the first time, we report a pixel-reassigned spectral-domain optical coherence tomography (OCT) with $\sim$1.5 ...
