High-speed spectroscopic OCT around 1550 nm based on dual-band swept laser source [PDF]

open access: yes, 2012
We report a 45 kHz spectroscopic OCT system based on a swept laser source utilizing two wavelength bands. The source is generated by single-band swept laser input and a fiber optical parametric amplifier.

Phase stable swept-source optical coherence tomography with active mode-locking laser for contrast enhancements of retinal angiography

open access: yesScientific Reports, 2021
Swept-source optical coherence tomography (SS-OCT) is an attractive high-speed imaging technique for retinal angiography. However, conventional swept lasers vary the cavity length of the laser mechanically to tune the output wavelength. This causes sweep-

Sensitivity advantage of swept source and Fourier domain optical coherence tomography [PDF]

open access: yes, 2003
We present theoretical and experimental results which demonstrate the superior sensitivity of swept source (SS) and Fourier domain (FD) optical coherence tomography (OCT) techniques over the conventional time domain (TD) approach. We show that SS- and FD-

Clinical utility of anterior segment swept-source optical coherence tomography in glaucoma

open access: yesOman Journal of Ophthalmology, 2016
Optical coherence tomography (OCT), a noninvasive imaging modality that uses low-coherence light to obtain a high-resolution cross-section of biological structures, has evolved dramatically over the years.

Imaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography. [PDF]

open access: yes, 2012
The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To
