PROBLEM TO BE SOLVED: To provide a fundus oculi spectral characteristic measuring apparatus and a method for measuring fundus oculi spectral characteristics highly accurately measuring spectral characteristics of the fundus oculi without causing deterioration in detection sensitivity.SOLUTION: This fundus oculi spectral characteristic measuring apparatus 1 applies light from a light source to the fundus oculi Sb of a subject's eye and guides the light emitted from the fundus oculi Sb through an objective lens to a first reflection section 16 and a second reflection section 15. Then, this apparatus causes an imaging lens to guide first and second reflected light beams reflected by the first and second reflection sections 16 and 15 to a same point, and causes a detecting section 24 to detect the intensity of interference light. The detecting section 24 detects a change in the interference light intensity while allowing a phase shifter 14 to extend or contract an optical path length difference between the first and second reflected light beams, and a processing section 30 finds an interferogram from the change in the interference light intensity. At that time, the processing section 30 calculates a distance from an intersection of the optical axis of the imaging lens and an imaging surface to a light receiving element, a focal length of the imaging lens, and an optical path length difference from a moving distance of the first reflected section 16, and corrects spectrum according to the optical path length difference.
