Patent ID: 8304746

Claim:
A fluorescence measurement device for a living body, comprising: an exciting light-irradiating device having a plurality of exciting light sources placed at mutually different positions for irradiating the sample with exciting light from various different directions; an electrical switch for controlling lighting of the exciting light sources; a fluorescence filter allowing only predetermined wavelength components of fluorescence emitted from a living sample placed on a sample holder to pass through; a two-dimensional detector for picking up a fluorescence image produced by fluorescence passed through the fluorescence filter; an image display device for displaying an image picked up by the detector, and a light guide optical system for guiding a plurality of fluorescence images to the two-dimensional detector to observe fluorescence emitted from the sample placed on the sample holder from a plurality of directions; wherein each of the exciting light sources of the exciting light-irradiating device has an optical filter for eliminating, from exciting light emitted from the exciting light source, at least wavelength components that are the same as that allowed to pass through the fluorescence filter.
