Patent ID: 7729732

Claim:
A biological information measuring apparatus comprising: a plurality of light emission means, each adapted for modulating a predetermined primary modulated signal by spread spectrum modulation to thereby generate a secondary modulated signal, and for injecting a light beam into a living organism on the basis of the secondary modulated signal; light detection means for receiving the light beams which have been emitted from the plurality of light emission means and transmitted through the living organism, for obtaining an electrical signal corresponding to the light beams through despreading, and for detecting a signal contained in the light beams on the basis of the electrical signal; and control means for controlling the operation of the light emission means and the light detection means, and for obtaining biological information associated with the metabolism of the living organism on the basis of the signal detected by the light detection means, wherein the control means comprises: spread code sequence acquisition means for acquiring, from each respective light emission means of the plurality of light emission means, a different spread code sequence employed by the respective light emission means for spread spectrum modulation of the predetermined primary modulated signal; and spread code sequence supply means for supplying, to each of the light detection means, some, but not all of the different spread code sequences acquired by the spread code sequence acquisition means.
