Abstract
An ophthalmologic imaging apparatus having an OCT optical system for acquiring OCT data of a tissue of a subject eye based on a spectral interference signal of measurement light emitted to the tissue and reference light. The apparatus further has a second optical system for acquiring a front image of the tissue; an optical element having asymmetry and arranged on a common optical path of the OCT optical system and the second optical system; and an arithmetic controller that associates an OCT data acquisition position with coordinates of the front image while taking at least a difference in distortion caused by the optical element between the OCT optical system and the second optical system into consideration.
