PROBLEM TO BE SOLVED: To achieve both high resolution and practicability in a fundus photographing apparatus.SOLUTION: In the fundus photographing apparatus, a first optical system scans the ocular fundus with an ultrashort pulse laser beam output from a first light source, and detects fluorescent light generated in a multiphoton excitation process by the ultrashort pulse laser beam radiated to the ocular fundus. A first image forming part forms a first image of the ocular fundus on the basis of the data acquired by the first optical system. A wave surface adjusting part adjusts a wave surface of the ultrashort pulse laser beam. A second optical system divides the beam from a second light source into a measuring beam and a reference beam, scans the ocular fundus with the measuring beam, and detects interference light generated by superposing the return light of the measuring beam from the ocular fundus and the reference beam. A second image forming part forms a second image of the ocular fundus on the basis of the data acquired by the second optical system. An optical path synthesizing part synthesizes an optical path of the ultrashort pulse laser beam and an optical path of the measuring beam.SELECTED DRAWING: Figure 1 |
