Application and progress of swept source optical coherence tomography in choroid-related diseases

open access: yesYanke Xuebao
Central serous chorioretinopathy (CSC) is one of the choroidal spectrum diseases, characterized by choriod thickening and increased vascular permeability. Therefore it is very important to observe choroid, as this allows us to monitor it and formulate an

Real-Time Experimental Measurement of Swept Source VCSEL Properties Relevant to OCT Imaging

open access: yesIEEE Photonics Journal, 2017
A real-time study of the dynamic properties of a frequency swept vertical cavity surface emitting laser (VCSEL) is presented. Such tunable laser sources have previously been shown to provide long coherence lengths and improved performance in metrology ...

Laser Lens Size Measurement Using Swept-Source Optical Coherence Tomography

open access: yesApplied Sciences, 2020
A high-speed, high-resolution swept-source optical coherence tomography (SS-OCT) is presented for focusing lens imaging and a k-domain uniform algorithm is adopted to find the wave number phase equalization.

Attenuation coefficient as a quantitative parameter for analyzing cataracts with optical coherence tomography [PDF]

open access: yesEPJ Web of Conferences, 2020
Crystalline lenses of mice were imaged in vivo with a custom-made swept-source optical coherence tomography system. The use of the attenuation coefficient as a quantitative parameter for investigating the lens opacities magnitude is proposed ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Signal-to-signal-to-noise ratio of full-field Fourier domain optical coherence tomography: experiment [PDF]

open access: yes, 2005
We report a new approach in optical coherence tomography (OCT) termed full-field Fourier-domain OCT (3F-OCT). A three-dimensional image of a sample is obtained by digital reconstruction of a three-dimensional data cube, acquired using a Fourier ...
