Abstract
An optical coherence tomographic imaging apparatus including a planar image obtaining unit configured to obtain a planar image of a subject based on a return beam from the subject irradiated by the irradiation unit that irradiates the subject with light of a first wavelength band, a tomographic image obtaining unit configured to obtain a tomographic image of the subject based on a beam in which a return beam from the subject irradiated with the laser beam emitted while sweeping a second wavelength range which is longer than the first wavelength band and a reference beam corresponding to the laser beam are combined, and a correction unit configured to correct an optical path length difference generated due to a difference between the first wavelength band and the second wavelength band.
