Claim One:
1. A Fourier ptychographic retinal imaging method, the method comprising: focusing on a retina of an eye, wherein focusing on the retina comprises moving one or both of the eye and a focusing lens to provide an optical path between the retina and the focusing lens that is approximately a sum of a focal length of the eye and a focal length of the focusing lens; illuminating the eye with plane wave illumination; acquiring, using one or more image sensors, a sequence of raw retinal images based on light reflected from the retina, wherein the sequence of raw retinal images is acquired while light reflected from the retina is passed by an aperture to the one or more image sensors as the aperture is sequentially shifted to different locations at the Fourier plane of an approximate plane of the retina, wherein the sequence of raw retinal images corresponds to regions in Fourier space; after acquiring the raw retinal images, reconstructing a complex full resolution image of the retina with phase image data recovered by iteratively updating regions in Fourier space with data from the plurality of raw retinal images; and correcting aberration in the reconstructed complex full resolution image of the retina to generate a substantially aberration-free, full resolution retinal image.
