Abstract
Aberration-corrected imaging of human photoreceptor cells, whether hardware or software based, presently requires a complex and often expensive setup. Here, we demonstrate a simple and inexpensive off-axis full-field time-domain optical coherence tomography approach to acquire volumetric data of in vivo human retina. Full volumetric, laterally phase stable data are recorded. The lateral phase stability allows computational aberration correction, which enables us to visualize single photoreceptor cells. In addition, our approach is able to correct large aberrations and is thus feasible for the numerical correction of ametropia in post processing. Our implementation of full-field OCT combines a low technical complexity with the possibility to use the phase of the recorded light for computational image correction.
