Swept source-OCT and swept source-OCT angiography findings in posterior microphthalmos

International Ophthalmology, 2019
To describe swept source-OCT (SS-OCT) and swept source-OCT angiography (SS-OCTA) findings in eyes with posterior microphthalmos (PM).Twelve eyes (six patients) with PM were evaluated using SS-OCT and SS-OCTA. Structural changes, subfoveal choroidal thickness (SFCT), and perifoveal capillary changes with qualitative and quantitative assessments were ...

Swept-source OCT and swept-source OCT angiography in glaucoma diagnostics

Spektrum der Augenheilkunde, 2017
Swept-source OCT (SS-OCT) has been introduced as a fast method for examining the retinal nerve fiber layer (RNFL) and, like OCT angiography (OCTA), the structure of vessels in the retina and the optic nerve head. The aim of this study was to assess whether SS-OCT is able to detect different patterns of glaucomatous nerve fiber layer defects and to ...

Full-field swept-source phase microscopy

Optics Letters, 2006
We present a full-field phase microscopy technique for quantitative nanoscale surface profiling of samples in reflection. This technique utilizes swept-source optical coherence tomography in a full-field common path interferometer for phase-stable cross-sectional acquisition without scanning.

Swept-source parallel OCT

SPIE Proceedings, 2009
By increasing the speed and reducing the complexity of OCT systems, the parallel OCT system presented here will reduce the cost of high performance instruments while making them more widespread and easy to use. The instrument integrates line scanning with a swept source to achieve ultrahigh image speeds in a much simpler way.

Networked Swept-Source Raman Sensors

Conference on Lasers and Electro-Optics, 2021
Raman spectroscopy with large-area, spectrally-selective detectors and tunable lasers enables distributed chemical sensing where excitation light can be delivered via optical datacom networks. Distributed sensing over 100’s of meters and multiple locations is demonstrated.

Wavelength swept ASE source

Optical Coherence Tomography and Coherence Techniques IV, 2009
We present a novel wavelength swept light source for Optical Coherence Tomography (OCT). Arbitrary sweep rates up to 2x170kHz are achieved by phase-shifted control of two optical bandpass-filters to compensate light propagation effects.

Swept source digital holographic phase microscopy

Optics Letters, 2016
We propose a swept source-based digital holographic phase microscopy technique. By scanning source wavelength, a series of on-axis interferograms can be obtained for accurate determination of the sample phase using spectral domain interferometry. With these sample spectra, sources of undesirable interference artifacts, often significant in holographic ...
