A light beam reflected from an ocular fundus 1a is split into a pair of right and left light beams by a two-aperture stop 31 disposed in a position conjugate with an anterior ocular segment 1b of an eye 1 to be examined. The pair of right and left ocular fundus images having a parallax is formed as intermediate images from the split light beams at the position of a photographic mask 43. The optical path of the pair of ocular fundus images formed as intermediate images is split by a pair of optical path splitting lenses 51, 52 disposed in a position substantially conjugate with the two-aperture stop. One ocular fundus image is re-formed on half of an imaging plane 53a of an imaging element 53, and the other ocular fundus image is re-formed separately on the other half of the imaging plane. With such a structure, two ocular fundus images for three-dimensional viewing can be efficiently obtained without using a prism for splitting the optical path. |
