Abstract:
1. An optical measurement apparatus comprising at least: a flow channel through which samples flow; first light radiation means for radiating light to said samples flowing through said flow channel; first light detection means for detecting optical information emitted from said samples due to said light radiated by said first light radiation means to said samples; first opto-electrical conversion means for carrying out an opto-electrical conversion process of converting said optical information detected by said first light detection means into an analog electrical signal; first analog-to-digital conversion means for carrying out an analog-to-digital conversion process of converting said analog electrical signal, which is output by said first opto-electrical conversion means, into a digital electrical signal; second light radiation means provided on the downstream side of said flow channel with respect to said first light radiation means for serving as a light radiation means for radiate light to said samples; second light detection means for detecting optical information emitted from said samples due to said light radiated by said second light radiation means; second opto-electrical conversion means for carrying out an opto-electrical conversion process of converting said optical information detected by said second light detection means into an analog electrical signal; amplification means for amplifying said analog electrical signal, which is output by said second opto-electrical conversion means, on the basis of said digital electrical signal output by said first analog-to-digital conversion means as a result of said analog-to-digital conversion process; and second analog-to-digital conversion means for converting said analog electrical signal amplified by said amplification means into a digital electrical signal.
