Publication number: 20110284770Abstract: A fluorescence detecting device generates a modulation signal for modulating an intensity of laser light and modulates the laser light by using the modulation signal, when receiving fluorescence emitted by a measurement object irradiated with laser light emitted from a laser light source unit. The fluorescence detecting device obtains a fluorescent signal of the fluorescence emitted by the measurement object irradiated with the laser light and calculates, from the fluorescent signal, the phase delay of the fluorescence with respect to the modulation signal. At the time, the fluorescence detecting device controls the frequency of the modulation signal so that the value of the phase delay comes close to a preset value. The fluorescence detecting device calculates the fluorescence relaxation time of the fluorescence emitted by the measurement object by using a phase delay obtained under the condition of frequency of the modulation signal at the time when the control is settled.Type: ApplicationFiled: February 8, 2010Publication date: November 24, 2011Applicant: MITSUI ENGINEERING & SHIPBUILDING CO., LTDInventors: Shigeyuki Nakada, Kyouji Doi

Publication number: 20110278471Abstract: In order to remove autofluorescence emitted by a measurement object, fluorescence of the measurement object within a first wavelength band is first received. The first wavelength band is set so that the intensity of fluorescence emitted by the measurement object irradiated with intensity-modulated laser light is higher than that of autofluorescence emitted by the measurement object irradiated with the laser light. Then, the autofluorescence within a second wavelength band different from the first wavelength band is received. A generated fluorescent signal of the first fluorescence and a generated fluorescent signal of the autofluorescence are mixed with a modulation signal for modulating the laser light to produce first fluorescence data and autofluorescence data, respectively. The autofluorescence data is multiplied by a predetermined constant, and the thus obtained result is subtracted from the first fluorescence data to produce third fluorescence data.Type: ApplicationFiled: January 15, 2010Publication date: November 17, 2011Applicant: MITSUI ENGINEERING & SHIPBUILDING CO., LTDInventor: Kazuteru Hoshishima
