摘要：
An optical measurement instrument for a living body including a first light irradiator for irradiating light from a first irradiation position in a small region as considered as a plan on the surface of a head of a subject into the inside of the head in the region in the direction of depth, a second light irradiator for irradiating light from a second irradiation position in the region into the inside of the head, a first detecting for detecting the first irradiated light to pass through the head in a first detection position in the region, a second detector for detecting the second irradiated light to pass through the head in a second detection position in the region, and a calculator for multiplication or addition of a first signal and a second signal in a calculator.
