Claim 0:
1. An ophthalmologic imaging apparatus comprising:
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;
a second optical system for acquiring a front image of the tissue;
an optical element having asymmetry and being arranged on a common optical path of the OCT optical system and the second optical system; and
a controller comprising a processor and memory with programming that matches an OCT data acquisition position with coordinates of the front image, accounting for at least a difference in distortion caused by the optical element between the OCT optical system and the second optical system; and
wherein the optical element is arranged on a common optical path of the OCT optical system and the second optical system; and
the optical element comprises a dichroic mirror that combines an optical path of the OCT optical system and an optical path of the second optical system.
