40 MHz Swept-Source Optical Coherence Tomography at 1060 nm Using a Time-Stretch and Supercontinuum Spectral Broadening Dynamics

IEEE Photonics Journal, 2022
We present an akinetically swept light source based on a spectrally broadened mode-locked laser in all normal dispersion optical fiber followed by a linear dispersive time stretch and a regenerative amplification stage.

Novel perspectives on swept-source optical coherence tomography [PDF]

International Journal of Retina and Vitreous, 2016
Technologies for multimodal digital imaging of vitreoretinal diseases have improved the accuracy of diagnosis and the depth of the knowledge of the mechanisms of disease and their response to treatments. Optic coherence tomography (OCT) has become a mandatory tool for the management and for the follow-up of retinal pathologies.
