A method and an apparatus for detecting fluorescence to distinguish between a sub mucosa and a mucosa immediately and easily. The sub mucosa of organic tissue is distinguished from and the mucosa thereof based on autofluorescence emitted from the organic tissue in response to stimulating light projected thereon. The distinction between the sub mucosa and the mucosa is made based on normalized intensity of the autofluorescence emitted from the organic tissue utilizing the fact that the spectrum of autofluorescence emitted from the sub mucosa is different from the spectrum of autofluorescence emitted from the mucosa.
