Computational lightfield ophthalmoscope

A computational lightfield ophthalmoscope device, comprising:

• a first light source configured to emit light in a first wavelength range;
• a second light source configured to emit light in a second wavelength range;
• a third light source configured to emit light in a third wavelength range;
• a first beam splitter arranged to project light, emitted from the first light source, onto an anterior segment of a patient's eye;
• a second beam splitter arranged to project light, emitted from the second light source, onto a posterior segment of the patient's eye;
• a third beam splitter arranged to focus light, emitted from the third light source, onto a point in the posterior segment of the patient's eye;
• a fourth beam splitter arranged to reflect light remitted from the patient's eye;
• a diffuser positioned to receive light reflected by the fourth beam splitter, and configured to provide a pattern based on the light reflected by the fourth beam splitter;
• and
• an image sensor configured to obtain one or more images of the pattern for simultaneous, or near simultaneous, determination of aberrations of the patient's eye and derivation of a high-resolution image of the anterior segment of the patient's eye and a high-resolution aberration-corrected image of the posterior segment of the patient's eye.

A computational lightfield ophthalmoscope device, comprising:

• a first light source configured to periodically emit light at a first frequency;
• a second light source configured to periodically emit light at a second frequency;
• a third light source configured to periodically emit light at a third frequency;
• a first beam splitter arranged to project light, emitted from the first light source, onto an anterior segment of a patient's eye;
• a second beam splitter arranged to project light, emitted from the second light source, onto a posterior segment of the patient's eye;
• a third beam splitter arranged to focus light, emitted from the third light source, onto a point in the posterior segment of the patient's eye;
• a fourth beam splitter arranged to reflect light remitted from the patient's eye;
• a diffuser positioned to receive light reflected by the fourth beam splitter, and configured to provide a pattern based on the light reflected by the fourth beam splitter;
• and
• a camera configured to obtain one or more plenoptic images based on the pattern for simultaneous, or near simultaneous, determination of aberrations of the patient's eye and derivation of high-resolution images of the anterior segment of the patient's eye and the posterior segment of the patient's eye.

A method, comprising:

• emitting, by a first light source of a lightfield ophthalmoscope device, light in a first wavelength range;
• emitting, by a second light source of the lightfield ophthalmoscope device, light in a second wavelength range;
• emitting, by a third light source of the lightfield ophthalmoscope device, light in a third wavelength range;
• projecting, by a first beam splitter of the lightfield ophthalmoscope device, the light, emitted from the first light source, onto a cornea of a patient's eye;
• projecting, by a second beam splitter of the lightfield ophthalmoscope device, the light, emitted from the second light source, onto a retina of the patient's eye;
• focusing, by a third beam splitter of the lightfield ophthalmoscope device, light, emitted from the third light source, onto a point in the retina;
• reflecting, by a fourth beam splitter of the lightfield ophthalmoscope device, light remitted from the patient's eye;
• providing, by a diffuser of the lightfield ophthalmoscope device, a pattern based on light reflected by the fourth beam splitter;
• and
• obtaining, by a lens-less camera of the lightfield ophthalmoscope device, one or more images of the pattern for synergistic determination of aberrations of the patient's eye and derivation of a high-resolution image of the cornea and/or high-resolution aberration-corrected image of the retina.
