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

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

Single-pixel imaging of the retina through scattering media [PDF]
, 2019 Imaging the retina of cataractous patients is useful to detect pathologies before the cataract surgery is performed. However, for conventional ophthalmoscopes, opacifications convert the lens into a scattering medium that may greatly deteriorate the ...
