Abstract

Apparatus and method for providing a three-dimensional image of an ocular retina (R). A source of light (S) flashes illumination on the examined eye (11) wherefrom reflected light is returned. The reflected light carries a first reflection returned from the cornea (CRN) and from the lens (LNS) and a second reflection returned from the retina (R). A fast gate (G) remains closed to block the first reflection and is opened for passage of the second reflection onto a detector (53), via s Shack-Hartmann device (35). Data derived by the Shack-Hartmann device is forwarded to a processing unit (55) coupled to the detector. The Shack-Hartmann device is then used in the conventional way to provide eye aberrations measurements, which are used to correct the second reflection. After eye-aberration correction, the second reflection is the net reflection from the retina. Illumination at different wavelengths permits to map corresponding layers of the retina.
