It has long been unclear in what degree the brain should be activated and how much the blood volume should be varied for controlling a signal by measuring the concentration of metabolic substance in the tissue or change of concentration thereof using the light and by using the result of measurement. The present invention provides an optical measuring system which can present the concentration of metabolic substance in the tissue which may be detected with a subject by itself or the target value of change of the concentration. Thereby, it is now possible for the subject by itself to more easily detect and control the concentration of metabolic substance in the tissue or change of concentration thereof. As a result, cerebral information can be extracted in direct to realize various applications such as control of the game machines and welfare facilities.

Light rays of a plurality of wavelengths which are modulated in intensity with a plurality of different frequencies are irradiated on a plurality of irradiation positions on the surface of a living body, and time-variable changes in living body transmitting light intensity levels corresponding to the respective wavelengths and the respective irradiation positions are measured at different positions on the surface Changes in concentration values of absorbers are determined from the living body transmitting light intensity levels and a measuring point is set on a perpendicular extending through an intermediate point between the incident point and each detection point to image a function of the living body. The measuring time is shortened by estimating fluctuation attributable to the living body, and a local change in hemodynamic movement can be measured by detecting light rays transmitting through the interior of the living body by light detection at two different sites (equidistant from the light incident point) on a subject and by separating only the local change in hemodynamic movement from an overall change in hemodynamic movement in the living body in accordance with a logarithmic difference between the two detection signals.
