An optical coherence tomographic imaging apparatus includes a wavelength-sweeping light source. The wavelength-sweeping light source includes an optical resonator in which a light amplifying medium and a dispersive element configured to give angular dispersion to light emitted from the light amplifying medium according to the wavelength are provided, and a wavelength selection element having a rotating mechanism. An arithmetic processing unit converts a selected wavelength obtained in correspondence with a rotation angle of the rotating mechanism into an optical frequency, and obtains a data string of interfering signals at equal optical frequency intervals by interpolation on the basis of data on interfering signals sampled in correspondence with the rotation angle. |
