Contrast-based sensorless adaptive optics for retinal imaging [PDF]

, 2015
Conventional adaptive optics ophthalmoscopes use wavefront sensing methods to characterize ocular aberrations for real-time correction. However, there are important situations in which the wavefront sensing step is susceptible to difficulties that affect

Eyesi direct ophthalmoscope simulator: an effective training tool for medical undergraduates

BMC Medical Education
Introduction Non-ophthalmologists often lack sufficient operational training to use a direct ophthalmoscope proficiently, resulting in a global deficit of basic ophthalmological skills among general practitioners.

Visualizing and enhancing axial resolution in nonconfocal adaptive optics ophthalmoscopy

, 2019
International audienceWe 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.

OCT en-face images from the retina with adjustable depth resolution in real time

, 1999
A source with adjustable coherence length is devised and used to illuminate an OCT for en-face imaging of the retina of the human eye in vivo. Two modes of operation are described. The added capability of adjusting the depth resolution in real time while

High-contrast and high-speed multimodal imaging platform: the adaptive optics-confocal rolling slit ophthalmoscope (AO-CRSO)

International audienceAdaptive optics imaging techniques are invaluable for cellular-level retina visualization. While AO Flood illumination ophthalmoscopes provide distortion-free, high-speed images, they lack contrast.
