  • Publication number: 20120085933
    Abstract: A fluorescence emitted by a measurement object at a measurement point is measured. When the fluorescence is measured, a measurement object is irradiated with laser light whose intensity is time-modulated by using a modulation signal at a predetermined frequency. Then, the fluorescence emitted by the measurement object is formed to a flux of the fluorescence having uniform distribution of light intensity, and a plurality of partial fluorescent signals are generated by receiving a plurality of divided portions of the flux of the fluorescence. At least some of the partial fluorescent signals are added altogether to generate a single fluorescent signal. Finally, a fluorescence relaxation time of the fluorescence emitted by the measurement object is calculated from the generated fluorescent signal by using the modulation signal. When fluorescence intensity of the fluorescence calculated from the fluorescent signal exceeds a predetermined threshold, the partial fluorescent signals to be added are limited in number.

  • Publication number: 20120029831
    Abstract: 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.

  • Publication number: 20120025098
    Abstract: 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.
