1. A multichannel photometric measurement apparatus, comprising:

  • a single signal generator for generating an initial signal, the initial signal containing a harmonic component for collectively generating a plurality of modulation signals;

    a light emitting device including a plurality of light sources that are respectively drivable by each of the plurality of modulation signals having different frequencies;

    a light detector for detecting a plurality of kinds of light emitted from the light emitting device; and

    discriminating means for discriminating a detected signal output from the light detector per frequency domain of each of the different frequencies for each of the modulation signals.
