Abstract

We exploit the intrinsic phase stability of akinetic swept source optical coherence tomography to demonstrate digital defocus correction in-vivo at a center wavelength of 1060nm. The high speed of 500kHz enables digital adaptive optics (AO) correction across a field of view of 1.8x1.5deg, currently limited by the employed galvo scanners. The source operates in a previously presented dual resolution mode OCT system (wide field >40deg, AO >3deg) with hardware based adaptive optics. The latter allows to efficiently combine hardware and digital AO, and to further optimize the AO imaging results. We demonstrate the digitally assisted AO performance for both structural imaging as well as for OCT angiography imaging across the full retina down to the choriocapillaris.
