Publikováno v: Ophthalmic Technologies XXXI.

Phase-sensitive optical coherence tomography (OCT) is emerging as an imaging modality that detects functional changes in the retina. Besides imaging photoreceptor function, recently, functional changes in the inner plexiform layer (IPL) have been det

Robust and automated computational adaptive optics using multiple randomized sub-apertures

Autor: Sazan Burhan, Clara Pfäffle, Katharina Gercke, Gereon Hüttmann, David Melenberg, Hendrik Spahr, Lisa Kutzner, Felix Hilge, Dierck Hillmann

Publikováno v: Optical Coherence Tomography and Coherence Domain Optical Methods in Biomedicine XXV.

Computational adaptive optics (CAO) is emerging as an attractive alternative to hardware-based solutions for diffraction-limited optical coherence tomography, e.g., of the human retina. Still, to become a reliable and robust solution, many challenges

Functional imaging of the retina with phase-sensitive full-field swept-source optical coherence tomography (Conference Presentation)

Autor: Felix Hilge, Katharina Gercke, Dierck Hillmann, Yoko Miura, Hendrik Spahr, Gereon Hüttmann, Clara Pfäffle, Sazan Burhan

Publikováno v: Quantitative Phase Imaging VI.

We demonstrate functional in vivo imaging of photoreceptor and neuronal layers within the living human retina by looking at the expansion of their optical path length. To this end, we use a special full-field swept-source optical coherence tomography

Improved functional imaging of ganglion neuronal and photoreceptor cell layers in living human retina (Conference Presentation)

Autor: Dierck Hillmann, Clara Pfäffle, Lisa Kutzner, Hendrik Spahr, Felix Hilge, Gereon Hüttmann, Sazan Burhan, Yoko Miura

Publikováno v: Optical Coherence Tomography and Coherence Domain Optical Methods in Biomedicine XXIV.

Non-invasive functional retinal imaging in humans is of tremendous interest. By using phase-sensitive full-field swept-source OCT (FF-SS-OCT) we demonstrated simultaneous quantitative imaging of the optical activation in the photoreceptor and ganglio

Functional imaging of neuronal layers in the human retina (Conference Presentation)

Autor: Felix Hilge, Dierck Hillmann, Yoko Miura, Lisa Kutzner, Gereon Hüttmann, Hendrik Spahr, Clara Pfäffle, Sazan Burhan

Publikováno v: Optical Coherence Tomography and Coherence Domain Optical Methods in Biomedicine XXIV.

Using phase-sensitive full-field swept-source optical coherence tomography we already showed that morphological changes in the photoreceptor outer segments are detectable. Those signals manifest themselves in an elongation of the optical path length.

Phase-sensitive interferometry of decorrelated speckle patterns

Autor: Dierck Hillmann, Lisa Kutzner, Clara Pfäffle, Hendrik Spahr, Gereon Hüttmann, Sazan Burhan, Felix Hilge

Publikováno v: Scientific Reports
Scientific Reports, Vol 9, Iss 1, Pp 1-15 (2019)

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. But moving scatterers or a fluctuating refractive index decorrelate the

Simultaneous functional imaging of neuronal and photoreceptor layers in living human retina

Autor: Lisa Kutzner, Yoko Miura, Gereon Hüttmann, Dierck Hillmann, Hendrik Spahr, Sazan Burhan, Clara Pfäffle, Felix Hilge

Publikováno v: Optics Letters. 44:5671

Functional retinal imaging, especially of neuronal activity non-invasively in humans, is of tremendous interest. Although the activation of photoreceptor cells (PRCs) could be detected in humans, imaging the function of other retinal neurons had been

Publikováno v: Optics Letters. 44:3905

Computational adaptive optics (CAO) is emerging as a viable alternative to hardware-based adaptive optics-in particular when applied to optical coherence tomography of the retina. For this technique, algorithms are required that detect wavefront erro
