Abstract: This fundus imaging device includes two or more curved mirrors, an illumination optical system, an image sensor, and a control unit. The illumination optical system irradiates the fundus of an eye under examination with slit-shaped illumination light via the two or more curved mirrors, and illuminates the fundus while moving the illuminated region. The image sensor can be disposed at a fundus-conjugate position, which is substantially optically conjugate with the fundus, and receives return light from the eye under examination. The control unit controls at least the illumination optical system. The longitudinal direction of an image formed by the illumination light on the fundus is substantially parallel to a plane that includes two or more focal points of the two or more curved mirrors. The control unit controls the illumination optical system so that the abovementioned image moves in a direction intersecting the longitudinal direction on the fundus.
