Abstract
A fundus camera and method of operating the fundus camera are described. The fundus camera includes an image sensor, an eyepiece lens, an illumination source, and an alignment target. The image sensor captures image light of a retina within an eye. The eyepiece lens is disposed to pass the image light of the retina to the image sensor. The illumination source is disposed to direct illumination light onto the retina through the eyepiece lens. The illumination source is further disposed around a first aperture through which the image light of the retina passes from the eyepiece lens to the image sensor. The alignment target is coupled to output an alignment image through the eyepiece lens to the eye and disposed around a second aperture through which the image light of the retina is passed to the image sensor and the illumination light is passed to the eyepiece lens.
