摘要:
A light beam reflected from an ocular fundus is split into a pair of right and left light beams by a two-aperture stop disposed in a position conjugate with an anterior ocular segment of an eye 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. The optical path of the pair of ocular fundus images formed as intermediate images is split by a pair of optical path splitting lenses disposed in a position substantially conjugate with the two-aperture stop. One ocular fundus image is re-formed on half of an imaging plane of an imaging element, and the other ocular fundus image is reformed 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.
