Classification: CPC G | IPC G

Claim 4:
5. A sample classification method for classifying a type of a sample, the sample classification method comprising:
obtaining a spectrum for each of samples and determining, through compressed sensing performed on spectra obtained, three or more measurement wavelengths to be used for reconstructing the spectrum, the spectrum being a transmission spectrum or an absorption spectrum;
(i) measuring, for each of samples whose types are known, wavelength components of the three or more measurement wavelengths, using the optical detection device according to claim 1, and (ii) generating reference data in which a measurement result obtained by measuring the samples whose types are known is associated with a corresponding one of the types; and
(i) measuring, for a sample whose type is unknown, wavelength components of the three or more measurement wavelengths, using the optical detection device, and (ii) determining a type of the sample by performing matching between a measurement result obtained by measuring the sample whose type is unknown and the reference data.
