Journal ArticleDOI
High-resolution optical coherence tomography over a large depth range with an axicon lens.
TL;DR: This work reports on the incorporation of an axicon lens into the sample arm of an interferometer to overcome the trade-off between lateral resolution and focusing depth when conventional optical elements are used.
Journal ArticleDOI
Real-time phase-resolved functional optical coherence tomography by use of optical Hilbert transformation
TL;DR: A novel real-time phase-resolved functional optical coherence tomography system that uses optical Hilbert transformation that has high sensitivity and a larger dynamic range for measuring the Doppler frequency shift that is due to moving red blood cells.
Journal ArticleDOI
Real-time phase-resolved optical coherence tomography and optical Doppler tomography
TL;DR: In this article, a real-time phase-resolved optical coherence tomography (OCT) and optical Doppler tomography system using optical Hilbert transformation (ODT) was developed.
Journal ArticleDOI
Phase-resolved functional optical coherence tomography: simultaneous imaging of in situ tissue structure, blood flow velocity, standard deviation, birefringence, and Stokes vectors in human skin.
TL;DR: A phase-resolved functional optical coherence tomography system that can simultaneously yield in situ images of tissue structure, blood flow velocity, standard deviation, birefringence, and the Stokes vectors in human skin is described.
