High-resolution retinal matrix imaging via computational motion and aberration correction
Aymeric Melt, Léo Puyo, Victor Barolle +3
High-resolution optical imaging of the human retina is essential for diagnosing ophthalmic and neurodegenerative diseases. While adaptive optics combined with coherence gating can…
Spatially or temporally resolved phase-based optoretinography with actively-tracked point-scanning optical coherence tomography
Léo Puyo, Jonas Franke, Felix Zeisberger +2
Optoretinography is a promising approach to measure visual function but its clinical translation has remained confined to research settings due to demanding hardware requirements.…
Measuring choriocapillaris blood flow with laser Doppler optical coherence tomography
Léo Puyo, Jonas Franke, Lisa Kutzner +3
We report on using a laser Doppler processing of Fourier-domain optical coherence tomography (OCT) data for the assessment of pulsatile blood flow in the choriocapillaris. Signal f…
Diffuse-illumination holographic optical coherence tomography
Léo Puyo, Clara Pfäffle, Hendrik Spahr +4
Holographic optical coherence tomography (OCT) is a powerful imaging technique, but its ability to reveal low-reflectivity features is limited. In this study, we performed holograp…
Real-Time Estimation of COVID-19 Infections: Deconvolution and Sensor Fusion
