    • An optical biometric system (1) is characterized by being provided with: a first received light amount information acquisition unit (25) which acquires skin blood flow data relating to a skin blood flow in a wide range of the scalp of a subject by controlling the transmission/reception of light to/from a light transmission/reception unit (30) using a wide-range control table; and a selection control table creation unit (24) which causes a storage unit (23) to store a selection control table for acquiring X pieces of first received light amount information (ΔA1) selected from among N pieces of first received light amount information (ΔA1), and in that when acquiring multiple pieces of measurement data relating to the brain activity in a predetermined range of the brain of the subject by controlling the transmission/reception of light to/from the light transmission/reception unit (30) using a control table, a light transmission/reception control unit (21) acquires skin blood flow data relating to a skin blood flow in a predetermined position of the scalp of the subject by controlling the transmission/reception of light to/from the light transmission/reception unit (30) using the selection control table.
    • 一种光学生物测定系统(1)的特征在于具有:第一接收光量信息获取单元(25),其通过控制所述第一接收光量信息获取单元(25)获取与被摄体的头皮的宽范围内的皮肤血流相关的皮肤血流数据 使用宽范围控制表发送/接收来自光发送/接收单元(30)的光; 以及选择控制表创建单元,其使存储单元(23)存储用于获取从N个第一接收光量信息中选择的X个第一接收光量信息(&Dgr; A1)的选择控制表 (&Dgr; A1),并且当通过控制到/从光发送/接收单元(30)的光的发送/接收来获取与被摄体的脑的预定范围内的大脑活动相关的多条测量数据 ),光发送/接收控制单元(21)通过控制来自/来自光的光的发送/接收来获取与被摄体的头皮的预定位置中的皮肤血流相关的皮肤血流数据 发送/接收单元(30)。
