Patent number: 8772739Abstract: A fluorescence detection device generates a modulation signal for modulating the intensity of the laser light and modulates the laser light using the modulation signal. The detection device obtains a fluorescent signal of the fluorescence emitted by the measurement object irradiated with the laser light, and calculates, from the fluorescent signal, a fluorescence intensity and the phase delay of the fluorescence with respect to the modulation signal. At the time, the detection device controls the operation amounts of the signal level of a DC component of the modulation signal and the gain of amplification just after the output of the fluorescent signal so that the value of a fluorescence intensity signal falls within a preset range. After the operation amounts are settled, the detection device calculates the fluorescence intensity and then calculates the fluorescence relaxation time of the fluorescence emitted by the measurement object using the phase delay.Type: GrantFiled: February 8, 2010Date of Patent: July 8, 2014Assignee: Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Shigeyuki Nakada, Kyouji Doi
