Optical coherence tomographic imaging method and optical coherence tomographic imaging apparatus

An optical coherence tomographic imaging method for imaging a tomographic image using interfering light caused by interference of return light of measurement light from an eye and reference light corresponding to said measurement light, said method comprising:

• a wavelength spectrum acquisition step to acquire the wavelength spectrum of said interfering light;
• an interpolate step in which a wavelength spectrum analysis unit interpolates the wavelength spectrum to increase its number of elements;
• a wavenumber spectrum acquisition step in which a wavelength spectrum analysis unit converts the interpolated wavelength spectrum into a wavenumber spectrum and decreases the number of elements to provide a wavenumber spectrum of substantially equal intervals;
• and
• a tomographic information acquisition step in which a wavelength spectrum analysis unit acquires tomographic information of said eye from said wavenumber spectrum of substantially equal intervals.
