<p>The present invention utilizes the difference of light reception data generated based on the difference in length of substantial optical diffusion paths (pa, pb) between a single light receiving point (C) and a plurality of irradiation points (A, B), or between a plurality of light receiving points (A, B) and a single irradiation point (C). According to the present invention, the inside information of substance based on the difference in length of the optical diffusion paths (pa, pb), may be measured. Even though measurements are made under different measuring conditions as to the part to be measured, the measuring time, etc., there may be obtained reliable measured data of the inside information with good reproducibility.</p> |
