<p><P>PROBLEM TO BE SOLVED: To compute the concentration of glucose contained in a corium layer while reducing the influence of noise caused by a layer other than the corium layer. <P>SOLUTION: An irradiation part 104 irradiates the skin with short-time pulse light, and a light receiving part 105 receives light backscattered by the skin. A measured light intensity acquiring part 106 acquires the received light intensity of the light receiving part 105 at the time t. An optical absorption coefficient computing part 109 computes an optical absorption coefficient of the corium layer of the skin based on light intensity acquired by the measured light intensity acquiring part 106, the optical path length of each layer of a skin model at the time t stored by an optical path length distribution storage part 102, and the light intensity of the skin model at the time t stored by a time-resolved waveform storage part 103. A concentration computing part 110 computes the glucose concentration of the corium layer based on the optical absorption coefficient of the corium layer computed by the optical absorption coefficient computing part 109. A plurality of light receiving parts 105 are prepared, and the light receiving parts 105 employed in this case have such irradiation light receiving intervals as to cause backscattering in desired layers. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
