<P>PROBLEM TO BE SOLVED: To provide a noiseless multichannel photometric apparatus. <P>SOLUTION: The multichannel photometric measurement apparatus includes: a light emitting device including a plurality of light sources that are respectively driven by a plurality of different frequencies; a light detector for detecting a plurality of kinds of light emitted from the light emitting device; and discriminating means for discriminating an output from the light detector per frequency domain. In the multichannel photometric measurement apparatus, a plurality of signals different by frequencies, which drive the light sources, are collectively generated by a single signal generator containing a harmonic component. <P>COPYRIGHT: (C)2012,JPO&INPIT |
