The present invention acquires spectral data for a CARS spectrum, or the like, of a sample at a high speed while suppressing data quantity. During scanning of irradiation light that is condensed and irradiated onto a sample, the exposure state of a detection unit of a spectroscope for dispersing light emitted from the sample is maintained, and spectral data is acquired in which spectrums occurring in a plurality of positions in the sample have been added. |
