Abstract
A fluorescence detecting method includes the steps of collecting a first fluorescence signal of the fluorescence received by a light receiving unit when the analyte passes a position irradiated with a laser beam, collecting a second fluorescence signal of the fluorescence received by the light receiving unit in the absence of the analyte at the position irradiated with the laser beam, and adjusting a first phase difference information on the first fluorescence signal with respect to the modulation signal by using a second phase difference information on the second fluorescence signal with respect to the modulation signal to obtain a third phase difference information on the fluorescence signal of the fluorescence, and obtaining a fluorescence relaxation time constant of the fluorescence based on the third phase difference information thus obtained.
