  • Patent number: 11911107
    Abstract: A method for imaging a tissue of an eye, the method including the steps of providing oblique illumination to the eye by a plurality of light emitting areas of a light delivery device, the plurality of light emitting areas being independently controllable and arranged to direct light towards at least one of a retina and an iris of the eye, causing an output beam from light backscattered from the at least one of the retina and the iris by the oblique illumination, capturing the output beam with an imaging system to provide a sequence of images of a fundus of the eye, and retrieving a phase and absorption contrast image from the sequence of images of the fundus, wherein the sequence of images of the fundus of the step of capturing is obtained by sequentially turning on one or more of the plurality of light emitting areas at a time in the step of providing the oblique illumination.

  • Publication number: 20220248952
    Abstract: An ophthalmic illumination and imaging system with transscleral/transpalpebral illumination of the eye fundus comprises a light-delivering device with a plurality of emitting areas; each of the emitting areas being configured to be independently controllable and directed towards the sclera of the intended eye to measure, providing transscleral oblique illumination of the eye fundus; an active eye aberration correcting system; and an imaging system configured to create multiple images of the eye fundus on multiple imaging sensors.
