Abstract: 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.

Abstract: A highly reliable optical measuring instrument for multi-channel simultaneous measurement has an intensity of light emitted from a light source modulated at different frequencies and the light is applied to multiple positions of a test object. The light which is detected from the test object is converted into electric signals by a photodiode, and modulation signals are detected by a lock-in amplifier module. The signals are processed as information on the test object interior by a processing unit. Light is applied sequentially from a light source in a preparatory measurement step prior to final measuring, and the signal level of the detection light is measured for each light applied position. A control unit controls light intensity and detection signal level to ensure that the difference in detection light levels is kept within a specified range.

In the case of measurement in a deep portion in the subject, a sampling point of a pair of the light source and the light detector which are disposed at a large interval is used.
