Polarization-sensitive swept-source optical coherence tomography with continuous source polarization modulation [PDF]

, 2008
We present fiber-based polarization-sensitive swept-source optical coherence tomography (SS-OCT) based on continuous source polarization modulation. The light source is a frequency swept laser centered at 1.31 μm with a scanning rate of 20 kHz.

Phase-stability optimization of swept-source optical coherence tomography [PDF]

Biomedical Optics Express, 2018
Phase-resolved imaging of swept-source optical coherence tomography (SS-OCT) is subject to phase measurement instabilities involved with the sweep variation of a frequency-swept source. In general, optically generated timing references are utilized to track the variations imposed on OCT signals.
