Abstract:
1. A measurement system, comprising: a measurement device for acquiring measurement data of fluorescence generated by irradiating a target measurement part of a living body with excitation light; and a measurement result processing device which processes the measurement data acquired by the measurement device, said measurement device including: a light-shielding section for shielding environment light which is directed toward the target measurement part of the living body; an excitation light source for irradiating the target measurement part of the living body with excitation light; and a detector for generating the measurement data by analyzing the fluorescence generated by irradiating the target measurement part with the excitation light, said measurement result processing device including: a feature extraction section configured to extract a fluorescence characteristic of fluorescence emitted from the target measurement part, which fluorescence is obtained by irradiating, with excitation light, the target measurement part of a living body; a substance amount specifying section configured to specify an amount of fluorescent substances contained in the target measurement part on the basis of the fluorescence characteristic extracted by the feature extraction section; a damage degree determination section configured to determine a damage degree indicative of a degree of damage received by the target measurement part or a part of the target measurement part on the basis of the amount of fluorescent substances specified by the substance amount specifying section; an age calculation section for calculating measurement part age indicative of how aging of the target measurement part progresses on the basis of actual age of the living body and the damage degree of the target measurement part, the actual age being entered to the measurement result processing device, the damage degree being determined by the damage degree determination section; and a correlation information storage section configured to store first correlation information indicative of a correlation between (I) the actual age of the living body, the average life expectancy, and the damage degree, and (II) the measurement part age, the age calculation section calculating the measurement part age by use of formula as the first correlation information;
