Abstract
According to one embodiment, a fundus imaging apparatus includes a light source, an optical scanner, an optical fiber, a light guide system, a photodetector unit, and an image forming unit. The optical scanner scans the fundus of a subject's eye with light from the light source. The optical fiber includes a plurality of optical waveguides. The light guide system guides the light returning from the fundus to the entrance end of the optical fiber. The photodetector unit detects light output from each of at least three regions at the exit end of the optical fiber. The image forming unit forms a first image based on a detection result of light output from a first region of the at least three regions, and a second image based on detection results of light output from two or more regions of the at least three regions other than the first region.
