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…

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…

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…
