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…
Retinal blood flow imaging with combined full-field swept-source optical coherence tomography and laser Doppler holography
Léo Puyo, Hendrik Spahr, Clara Pfäffle +2
Full-field swept-source optical coherence tomography (FF-SS-OCT) and laser Doppler holography (LDH) are two holographic imaging techniques presenting unique capabilities for ophtha…
Real-Time Estimation of COVID-19 Infections: Deconvolution and Sensor Fusion
Maria Jahja, Andrew Chin, Ryan J. Tibshirani
We propose, implement, and evaluate a method to estimate the daily number of new symptomatic COVID-19 infections, at the level of individual U.S. counties, by deconvolving daily re…
Phase-sensitive interferometry of decorrelated speckle patterns
Dierck Hillmann, Hendrik Spahr, Clara Pfäffle +4
Phase-sensitive coherent imaging exploits changes in the phases of backscattered light to observe tiny alterations of scattering structures or variations of the refractive index. B…
Functional imaging of ganglion and receptor cells in living human retina by osmotic contrast
Clara Pfäffle, Dierck Hillmann, Hendrik Spahr +5
Imaging neuronal activity non-invasively in vivo is of tremendous interest, but current imaging techniques lack either functional contrast or necessary microscopic resolution. The…
Off-axis reference beam for full-field swept-source OCT and holoscopy
Dierck Hillmann, Hendrik Spahr, Helge Sudkamp +4
In numerous applications, Fourier-domain optical coherence tomography (FD-OCT) suffers from a limited imaging depth due to signal roll-off, a limited focal range, and autocorrelati…
Aberration-free volumetric high-speed imaging of in vivo retina
Dierck Hillmann, Hendrik Spahr, Carola Hain +5
Research and medicine rely on non-invasive optical techniques to image living tissue with high resolution in space and time. But so far a single data acquisition could not provide…
In vivo optical imaging of physiological responses to photostimulation in human photoreceptors
Dierck Hillmann, Hendrik Spahr, Clara Pfäffle +3
Non-invasive functional imaging of molecular and cellular processes of vision is expected to have immense impact on research and clinical diagnostics. Although suitable intrinsic o…
