Abstract
A biological information measuring apparatus includes a plurality of light emission sections, a plurality of light detection sections, and a control section. Each light emission section injects, into a living organism, a spectrum-modulated light beam having a specific wavelength. The control section acquires a spread code sequence employed by each of the light emission sections for spread spectrum modulation, and supplies the spread code sequence to the light detection sections. By use of the spread code sequence, each light detection section selectively receives a specific reflected light beam having the spread code sequence, which is selected from among the light beams which have been emitted from the light emission sections and reflected in the living organism. Subsequently, each light detection section despreads an electrical signal corresponding to the thus-received reflected light beam, and outputs a detection signal corresponding to the intensity of the reflected light beam.
