<P>PROBLEM TO BE SOLVED: To provide a laser scanning method for measuring in vivo amount of a specific substance, which can quantitatively and non-invasively measure the concentration and distribution of lutein in ocular fundus. <P>SOLUTION: The laser scanning method for measuring an in vivo amount of a specific substance is characterized in measuring the density of the lutein from a signal intensity level of an anti-stokes ray by causing the wavelength of the anti-Stokes ray to be greater than a wavelength absorption band of a specific substance, shifting the wavelength of a probe light by the amount of shifting in Raman scattering of the specific substance from the wavelength of the anti-Stokes ray, and shifting the wavelength of a Stokes light by the amount of shifting in Raman scattering of the specific substance from the wavelength of the probe light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
