PROBLEM TO BE SOLVED: To provide resampling processing in consideration of wavenumber change characteristics of a light source.SOLUTION: A resampling method is provided in a data processor to which an optical coherence tomography is applied, the method irradiating a target object by sweeping the wavelength of light from a light source and obtaining light reflected from the object as an interference waveform signal from an interferometer. The resampling method includes obtaining the interference waveform signal and elapsed time from the start of operation of the light source, and, on the basis of the obtained lapsed time, referring to a data table storing wave number - time functions according to elapsed time from the start of operation of the light source to determine the wave number - time function of light from the light source. Then, the resampling method includes obtaining a resampling point of the interference waveform signal where the wave number of the wave number - time function obtained by referring to the data table is set at a regular interval, and resampling the interference waveform signal at the resampling point. |
