Title:
蛍光検出装置及び蛍光検出方法
Document Type and Number:
Japanese Patent JP4606518
Kind Code:
B2
Abstract:
Disclosed herein is a fluorescence detecting device intended to improve the measurement accuracy of a fluorescence relaxation time. The fluorescence detecting device includes a laser light source unit that irradiates a measurement object with laser light, a light-receiving unit that outputs a fluorescent signal of fluorescence emitted by the measurement object irradiated with the laser light, a light source control unit that generates a modulation signal for time-modulating an intensity of the laser light emitted from the laser light source unit by at least two frequency components, and a processing unit that determines a fluorescence relaxation time of the fluorescence emitted by the measurement object by using the fluorescent signal outputted by the light-receiving unit and the modulation signal, wherein the processing unit determines phase delays of the fluorescent signal with respect to the modulation signal at the at least two frequency components, and determines a fluorescence relaxation time at each of the frequency components by using the phase delay, and determines an average fluorescence relaxation time by weighted averaging of the fluorescence relaxation times.
