Abstract

We propose a study to better understand the impact of dynamic ocular aberrations in the axial resolution of nonconfocal adaptive optics (AO) ophthalmoscopes via a simulation of the 3D PSF in the retina for various AO-loop rates. We then use Optical Incoherence Tomography (OIT), a method enabling the generation of tomographic retinal cross-sections in incoherent imaging systems, to evaluate the benefits of a fast AO-loop rate on axial resolution and consequently on AO-corrected retinal image quality. We used the PARIS AO flood- illumination ophthalmoscope (FIO) for this study, where retinal images from different focal planes at an AO-loop rate of 10 Hz and 50 Hz were acquired.
