Abstract

A flood-illuminated adaptive optics ophthalmoscope for retinal multilayer imaging is introduced in this paper. By arranging an alterable stop in the illumination path, the illuminated area of retinal layer can be changed. A laser beacon for wavefront sensing is formed when the stop is a narrow aperture. The large aperture allows flood illumination and expands imaging field. A moveable imaging camera can focus on different layers of the retina. In the confirming experiment, a subject who was a 25-years-old normal health Chinese male was imaged. We got clear images of photoreceptor layer, blood vessels and nerve fiber layer.
