1. A pulse photometer adapted to observe a pulse wave of a living body, comprising a light emitter, adapted to irradiate the living body with a first light beam having a first wavelength and a second light beam having a second wavelength which is different from the first wavelength;

  • a converter, operable to convert the first light beam and the second light beam, which have been reflected or transmitted from the living body, into a first data set corresponding to the first wavelength and a second data set corresponding to the second wavelength; and

    a processor, operable to process the first data set and the second data set with a rotating matrix to separate a signal component and a noise component contained in the pulse wave.
