ABSTRACT:
A fluorescence detecting system detects auto fluorescence emitted from an intrinsic pigment in a part of an organism. An excitation light projector intermittently projects onto the part excitation light in the wavelength range which can excite the intrinsic pigment of the organism to emit auto fluorescence. A fluorescence detector extracts an auto fluorescence component in a desired wavelength range from auto fluorescence emitted from the pigment. A net auto fluorescence component in the desired wavelength range is obtained by subtracting a base line component in the desired wavelength range the fluorescence detector detects when the part of the organism is not exposed to the excitation light from a gross auto fluorescence component in the desired wavelength range the fluorescence detector detects when the part of the organism is exposed to the excitation light. A divider carries out a division between a first part of the net auto fluorescence component in the desired wavelength range and a second part of the same.
