Data Compressed Photonic Time-Stretch Optical Coherence Tomography [PDF]

, 2016
Photonic time stretch enables real-time optical coherence tomography, but at the cost of extreme requirement for high-speed signal acquisition and massive data set. This work reports a data compressed real-time Fourier-domain optical coherence tomography

Cumulative Sum Analysis for the Learning Curve of Optical Coherence Tomography Assisted Diagnosis of Basal Cell Carcinoma

Acta Dermato-Venereologica, 2020
The amount of training needed to correctly interpret optical coherence tomography scans of the skin is undefined. The aim of this study was to illustrate how cumulative sum charts can be used to determine how many optical coherence tomography scans ...

Optical tomography dynamics induced by qubit-resonator interaction under intrinsic decoherence

Scientific Reports, 2022
A superconducting circuit with a qubit and a resonator coupled via a two-photon interaction is considered. When the resonator is initially in a superposition of coherent states, optical tomography and quantum coherence dynamics are examined in the ...

All fiber polarization insensitive detection for spectrometer based optical coherence tomography using optical switch

, 2019
Polarization dependent image artifacts are common in optical coherence tomography imaging. Polarization insensitive detection scheme for swept source based optical coherence tomography systems is well established but is yet to be demonstrated for all ...

Retinal vascular occlusion in pregnancy: three case reports and a review of the literature

Journal of Medical Case Reports, 2022
Background Retinal arterial occlusive events in young patients are rare. However, because of physiological multifactorial adaptations during pregnancy, retinal vascular occlusive disease may occur spontaneously.

Design and characterization of SiON integrated optics components for optical coherence tomography [PDF]

, 2009
Optical coherence tomography (OCT) is a technique for high resolution imaging of biological tissues with a depth range of a few millimeters. OCT is based on interferometry to enable depth ranging.
