[Problem] To provide a device for generating a three-dimensional retina image enabling detection of shifting of a scanning position during retinal scanning by a simple configuration, and also making it possible to obtain a retina image in which the impact of image distortion caused by such positional shifting of the retina has been reduced. [Solution] A device (100) for generating an optical tomographic fundus image constituted of: a second light source unit (210) for outputting a line beam for forming a linear image on the retina (R) in order to detect movement of the retina (R); a positional shifting detection unit (220) for detecting a line reflection beam reflected by the retina (R) and detecting shifting of a scanning position during scanning of the retina; and a dichroic mirror (230) for propagating the line beam on the same optical path in an inspection unit (140) as that of an object light scanning beam. |
