REFLECTION DETECTION TYPE MEASUREMENT APPARATUS FOR SKIN AUTOFLUORESCENCE
First Claim
1. A reflection detection type measurement apparatus for skin fluorescence, the apparatus comprising:
- a first light source irradiating excitation light on a measurement target;
a second light source irradiating light of a wavelength different from that of light from the first light source on the measurement target;
a first optical detector detecting a reflected light generated from the measurement target due to the excitation light of the first light source; and
a second optical detector detecting a skin fluorescence generated from the measurement target due to the excitation light of the first light source, and detecting a reflected light generated from the measurement target due to the excitation light of the second light source;
wherein the first optical detector is disposed in an area other than a total reflection area to which the excitation light of the first light source is reflected after irradiating to the measurement target, and the second optical detector is disposed in an area other than a total reflection area to which the excitation light of the first light source and the light of the second light source are reflected after irradiating to the measurement target.
