Blood glucose measurement device, blood glucose calculation method, and blood glucose calculation program

Provided are a blood glucose measurement device, a blood glucose calculation method, and a blood glucose calculation program with which blood glucose levels can be accurately measured using light. Theblood glucose measurement device includes: a light source 1 that outputs measurement light L1 that is caused to enter a living body 50; a light detector 12 that detects the measurement light L1 propagating within the living body 50 and generates a detection signal according to the intensity of the measurement light L1; and a computing unit that computes the time lag between the time variation ofa first parameter relating to oxygenated hemoglobin concentration and the time variation of a second parameter relating to deoxygenated hemoglobin concentration on the basis of the detection signal, and computes data relating to the blood glucose level on the basis of the time lag. 本发明提供能够使用光高精度地测定血糖值的血糖值测定装置、血糖值计算方法和血糖值计算程序，血糖值测定装置包括：光源(11)，其输出向生物体(50)输入的测定光(L1)；光检测器(12)，其检测在生物体(50)的内部传播的测定光(L1)，生成与测定光(L1)的强度相对应的检测信号；和运算部
