A system for imaging a retina of an eye includes a first lens for positioning proximate to the eye; a light source positioned to illuminate the eye when the system is aligned with the eye; an image sensor adapted to capture a retinal image of the retina through the first lens; an aperture disposed along an optical path extending from the image sensor and passing through the first lens; and a processing apparatus communicatively coupled to the image sensor and the light source, wherein the processing apparatus includes logic that when executed by the processing apparatus causes the system to perform operations including: illuminating the eye with the light source and capturing the retinal image with the image sensor.

Focus stacking for retinal imaging

A system for imaging a retina includes an optical relay system having a first lens for positioning proximate to an eye, a light source positioned to illuminate the eye, an image sensor positioned to capture a retinal image of the retina through the first lens, an aperture disposed between the image sensor and the first lens along an optical path extending from the image sensor through the first lens, and a processing apparatus. The aperture surrounds the optical path and is adapted to block off-axis reflections from the eye.

A method of imaging an interior of an eye includes illuminating the interior of the eye with one or more beams of light from a light source, and said illuminating is configured to trigger a change to a pupil of the eye. An image sensor captures a sequence of images of light reflected by the interior of the eye during an expected timeframe when a width of the pupil is changing in response to said illuminating. A processing apparatus combines images in the sequence of images to form a composite image having a larger depth of field than a depth of field of each of the images in the sequence of images. The depth of field for each of the images corresponds to the width of the pupil when each of the images is captured.
