摘要：
The present invention addresses the problem of easily leveling a plurality of data obtained at different measurement sites by functional near-infrared spectroscopy into data having an optimal SN ratio. To solve the problem, the present invention provides a device 1 provided with: a measurement unit 6 disposed at a point at which probes PR1-PR3 which radiate or detect light and which each have an optical attenuator 13 form an equilateral triangle； and a control unit 2 for setting the transmittance of all the optical attenuators 13 so that the quantity of light radiated by the probes has a desired value, specifying a first channel in which the detected light quantity is greatest from among three channels to be measured, performing the abovementioned detection in second and third channels positioned between a third probe and first and second probes at both ends, adjusting the transmittance of the optical attenuator 13 of the first or second probe disposed at one end of the channel in which a smaller light quantity is detected so that the detected light quantities in the second and third channels are equal, adjusting the transmittance of the optical attenuator 13 of the third probe so that the detected light quantity in the second or third channel is equal to the detected light quantity in the first channel, and performing measurement while maintaining the adjusted total transmittance.La présente invention aborde le problème de nivellement aisé d'une pluralité de données obtenues à différents sites de mesure par spectroscopie infrarouge proche fonctionnelle en données ayant un rapport signal/bruit optimal. Pour résoudre le problème, la présente invention concerne un dispositif 1 pourvu de : une unité de mesure 6 disposée à un point auquel des sondes PR1-PR3 qui rayonnent ou détectent de la lumière et qui comportent chacune un atténuateur optique 13 forment un triangle équilatéral； et une unité de commande 2 pour régler la transmittance de tous les atténuateurs optiques
