Publication number: 20120029831Abstract: A fluorescence detecting device receives fluorescence emitted by n kinds of measurement objects within wavelength bands FLk (k is an integer of 1 to n) set so that the fluorescence intensity of fluorescence emitted by a measurement object k becomes higher than that of fluorescence emitted by the other one or more measurement objects, and acquires fluorescent signals corresponding to the wavelength bands FLk (k is an integer of 1 to n). Each of the fluorescent signals is subjected to frequency-down conversion by mixing it with a modulation signal for modulating the intensity of a laser beam Lk (k=1) corresponding to at least one of the wavelength bands FLk to produce fluorescence data including the phase delay and intensity amplitude of the fluorescent signal. The fluorescence data is corrected to calculate the phase delay and a fluorescence relaxation time is calculated using the phase delay.Type: ApplicationFiled: January 15, 2010Publication date: February 2, 2012Applicant: MITSUI ENGINEERING & SHIPBUILDING CO., LTDInventors: Kazuteru Hoshishima, Shigeyuki Nakada

Publication number: 20120025098Abstract: When receiving fluorescence emitted by a measurement object irradiated with laser light emitted from a laser light source unit, 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 fluorescence 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 fluorescence 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.Type: ApplicationFiled: February 8, 2010Publication date: February 2, 2012Applicant: MITSUI ENGINEERING & SHIPBUILDING CO., LTD.Inventors: Shigeyuki Nakada, Kyouji Doi
