ABSTRACT:
Deterioration of the resolution of tomographic images obtained by optical tomography measurement is prevented. Interference signals, which are obtained when a light beam L is emitted, are divided into a plurality of divided interference signals each having different wavelength bands. Spectral analysis is administered for each of the plurality of divided interference signals, to obtain a plurality of pieces of intermediate tomographic data. The plurality of pieces of intermediate tomographic data are employed to obtain tomographic data, a tomographic image is generated based on the tomographic data, then displayed.
