FLUORESCENCE INTENSITY MEASUREMENT DEVICE, AND METHOD OF MEASURING FLUORESCENCE INTENSITY

Abstract: a fluorescence intensity measurement device includes: a light source to emit, to a measurement target, a plurality of pieces of pulse-shaped excitation light of which a pulse width is modulated; a cmos image sensor to detect, as an image for each pulse of a piece of the plurality of pieces of pulse-shaped excitation light, fluorescence emitted from the measurement target by the piece of the plurality of pieces of pulse-shaped excitation light; and a controller to calculate a fluorescence intensity of the fluorescence. the controller calculates the fluorescence intensity of the fluorescence, based on two duty ratios of the two pieces of pulse-shaped excitation light having different pulse widths, and two light intensities obtained from the images detected by the two pieces of pulse-shaped excitation light.
