Multichannel photometric measurement apparatus

摘要

A multichannel photometric measurement apparatus according to one embodiment includes: 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.
