Abstract:
1. An optical measurement apparatus for living body comprising: a measurement channel including an irradiation use optical fiber which is set at an irradiation position on a body surface in an inspection area of a subject and irradiates an inspection light having a predetermined frequency of from visible to near infrared range and a light receiving use optical fiber which is set at a light receiving portion adjacent the irradiation use optical fiber on the body surface in the inspection area and receives the inspection light irradiated from the adjacent irradiation use optical fiber and penetrated through inside the subject; a light detection unit which detects the amount of inspection light received by the light receiving use optical fiber in an electrical signal; and a signal calculation and processing unit including a hemoglobin signal calculating unit which calculates a hemoglobin signal representing a hemoglobin concentration inside the subject through which the inspection light has penetrated based on the electrical signal detected by the light detection unit and an optical fiber setting adequacy evaluation unit which evaluates adequacy of setting on the body surface in the inspection area of the irradiation use optical fiber or the light receiving use optical fiber both of which constitute the measurement channel, wherein:
