Abstract:
A fluorescence diagnosis system comprisingan exciting light projecting means which projects light onto an organic part to be observed exciting light which is in a predetermined wavelength range suitable for exciting intrinsic fluorophore of the organic part to emit auto fluorescence, a detecting means which detects the intensity of the auto fluorescence emitted from the intrinsic fluorophore of the organic part to be observed upon excitation by the exciting light, a characteristic value obtaining means which obtains a plurality of characteristic values from the intensity of the auto fluorescence detected by the detecting means, and a recognizing means which recognizes the condition of the organic part observed on the basis of the characteristic values, in which the characteristic values comprise an intensity of the auto fluorescence and a normalized value of the intensity of the auto fluorescence, or a fluorescence yield of the auto fluorescence and a normalized value of the intensity of the auto fluorescence.
