Multidimensional en-face OCT imaging of the retina. [PDF]

, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...

Critical Role of Polymer Gate Dielectrics on the Charge Carrier Transport in Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Orbital Cavernous Hemangioma Presenting with a Dome-Shaped Maculopathy-Like Appearance on Swept-Source Optical Tomography Imaging

Case Reports in Ophthalmological Medicine, 2020
A 43-year-old patient presented with painless proptosis, limited upgaze, and vision loss in the right eye. Funduscopic examination revealed right optic disc edema and subtle macular compression. Swept-source optical coherence tomography (SS-OCT) revealed

Comparison of choroidal thickness measurements between spectral domain optical coherence tomography and swept source optical coherence tomography in children

Scientific Reports, 2021
Choroidal thickness is associated with many ocular conditions, interchangeability among different generations of optical coherence tomography is therefore important for both research purpose and clinical application.

Beyond backscattering: Optical neuroimaging by BRAD

, 2018
Optical coherence tomography (OCT) is a powerful technology for rapid volumetric imaging in biomedicine. The bright field imaging approach of conventional OCT systems is based on the detection of directly backscattered light, thereby waiving the wealth ...

Megahertz all-optical swept-source optical coherence tomography based on broadband amplified optical time-stretch [PDF]

, 2014
We demonstrate all-optical ultrahigh-speed swept-source optical coherence tomography (OCT) based on amplified optical time-stretch (AOT). Such an inertia-free wavelength-swept mechanism, via group velocity dispersion, enables us to realize OCT with an A ...

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

Advanced Functional Materials, EarlyView.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Swept source optical coherence tomography and optical coherence tomography angiography in pediatric enhanced S-cone syndrome: a case report

Journal of Medical Case Reports, 2018
Background Enhanced S-cone syndrome is an autosomal recessive retinal dystrophy related to a defect in a nuclear receptor gene (NR2E3) that leads to alteration in cells development from rod to S-cone. This retinal dystrophy may be associated with retinal

Slow light with a swept-frequency source

, 2010
We introduce a new concept for stimulated-Brillouin-scattering-based slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources.
