Non-invasive imaging of subsurface paint layers with optical coherence tomography [PDF]

, 2007
Optical coherence tomography (OCT) systems are fast scanning infrared Michelson interferometers designed for the non-invasive examination of the interiors of the eye and subsurface structures of biological tissues.

Visible spectrum extended-focus optical coherence microscopy for label-free sub-cellular tomography

, 2017
We present a novel extended-focus optical coherence microscope (OCM) attaining 0.7 {\mu}m axial and 0.4 {\mu}m lateral resolution maintained over a depth of 40 {\mu}m, while preserving the advantages of Fourier domain OCM.

Comparison of Adaptive Optics Scanning Light Ophthalmoscopic Fluorescein Angiography and Offset Pinhole Imaging [PDF]

, 2014
Recent advances to the adaptive optics scanning light ophthalmoscope (AOSLO) have enabled finer in vivo assessment of the human retinal microvasculature. AOSLO confocal reflectance imaging has been coupled with oral fluorescein angiography (FA), enabling

Glaucomatous vertical vessel density asymmetry of the temporal raphe detected with optical coherence tomography angiography. [PDF]

, 2020
Changes in retinal vasculature and ocular circulation may play an important role in the glaucoma development and progression. We evaluated the vertical asymmetry across the temporal raphe of the deep retinal layer vessel density, using swept-source ...

Immediate diagnosis of cutaneous metastases with optical coherence tomography, line‐field confocal optical coherence tomography and dermoscopy: A case series

JEADV Clinical Practice
Background Cutaneous metastases (CM) are a frequent finding in the follow‐up of malignant tumours. Objectives CM were examined with dermoscopy, optical coherence tomography (OCT), dynamic OCT and line‐field confocal OCT (LC‐OCT) to describe common ...

Gabor fusion technique in a Talbot bands optical coherence tomography system [PDF]

, 2012
In this paper we show how to advantageously combine two effects to enhance the sensitivity with depth in Fourier domain (FD) optical coherence tomography (OCT): Talbot bands (TB) and Gabor-based fusion (GF) technique.

Path-Length-Resolved Dynamic Light Scattering: Modeling the Transition From Single to Diffusive Scattering [PDF]

, 2000
Dynamic light-scattering spectroscopy is used to study Brownian motion within highly scattering samples. The fluctuations of the light field that is backscattered by a suspension of polystyrene microspheres are measured as power spectra by use of low ...
