Abstract
The distribution of abnormal tissue, such as lesions, in an observed object is precisely detected regardless of the distribution of absorbing material present in a living organism. Provided is a fluorescence imaging apparatus () including an excitation-light radiating unit () that irradiates an observed object with excitation light of a plurality of wavelengths; a filter () that transmits fluorescence in a specific wavelength band from among fluorescence produced by the observed object in response to the excitation light radiated from the excitation-light radiating unit (); a light detector () that detects the fluorescence transmitted through the filter (); and a computing unit () that calculates a fluorescence intensity ratio in the same wavelength band in response to the excitation light of the plurality of wavelengths, which is detected by the light detector ().
