<p>A biological photometric device characterized by an arranging method for a light irradiating unit and light detecting unit capable of measuring depth-based concentrations and the distribution of concentration changes when the concentration of an in-vivo metabolite and its concentration changes are image-measured, wherein, when the light irradiating unit and light detecting unit are disposed on a sample to be examined with a measuring point existing approximately at the midpoint between the two units, the concentration of an in-vivo metabolite and its concentration changes at a shallow portion of the sample to be examined are measured at a measuring point with the interval between the two units kept small, and a measurement at a deep portion thereof is conducted at a measuring point with the interval between the two units kept large.</p> |
