Abstract: The present disclosure relates to a retina imaging method in which a light from a light source into two lights is dispersed, at least one eyeground image of the eyeball at a first magnification is obtained by adjusting the paths of the two lights incident on the eyeball, and a plurality of DIC images are obtained at a second magnification higher than the first magnification with respect to the retina of the entirety of the obtained at least one eyeground image by adjusting the paths of the two lights incident on the eyeball.
