<P>PROBLEM TO BE SOLVED: To perform calibration of a spectrometer, etc. of an optical tomographic imaging apparatus such as a wavelength scanning type OCT or a Fourier domain OCT without using a special device such as an oscilloscope, an interference filter or the like. Ž<P>SOLUTION: When acquiring wavelength spectra of a reference light and a reflected light from a measurement object as a spectrum interference signal by the spectrometer 21 to calibrate the spectrometer 21 of the Fourier domain optical coherence tomography 18 which performs a Fourier conversion of the spectrum interference signal to extract a signal in an actual space, the spectrometer 21 is monitored by the Fourier domain optical coherence tomography 18 to calculate a distribution condition of a wavelength component spatially spread from the spectrum interference signal at a wavelength spectrometer and calibrate spatial distribution of spectral characteristics.
