Eye imaging methods and devices with reflection reduction
An imaging device for imaging an eye includes an eyepiece, an illumination system, an imaging system, and a controller. The illumination system includes a light source that emits illumination light along an illumination path through the eyepiece to the eye to produce a retinal diffuse reflection and a corneal specular reflection. The imaging system includes a first camera that captures a retinal image based on the retinal diffuse reflection and a first set of optical elements, a second camera that captures a corneal specular reflection image based on the corneal specular reflection and a second set of optical elements. The first camera captures at least some residual corneal specular reflection in the retinal image. The controller subtracts the residual corneal specular reflection from the retinal image based on the corneal specular reflection image.
