Abstract
In this work we present a retinal imaging system that incorporates full-field (FF) swept-source (SS) optical coherence tomography (OCT) with hardware adaptive optics (AO) correction operating in real time. We demonstrate that this configuration permits resolution of foveal cones, with volume rates adequate to measure light-evoked changes in photoreceptors. With the OCT reference arm blocked, the system is a high speed (kHz) AO flood illumination (FI) camera, supporting future studies of optoretinographic responses through common path interference. The characterization and demonstration of the system performance with in vivo human photoreceptor mosaic are presented.
