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…

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…
