Abstract
PROBLEMS The present invention provides the hemoglobin quantifying apparatus which is capable of clearly quantifying the oxygen metabolic state of biological tissue by calculating and quantifying the hemoglobin amount of biological tissue in a non-contact and non-invasive manner. SOLUTION The present invention provides the light receiver unitfor receiving any two narrow wavelength band components and white components having reflection characteristics different according to the oxygen saturation of hemoglobin, which are reflected from the biological tissue a, and the hemoglobin amount calculation unitfor calculating the hemoglobin amount based on the light components in the two narrow wavelength bands obtained from the received light components, and the hemoglobin amount calculation unitfor correcting the light components in the two narrow wavelength bands based on the blue and green components to calculate the hemoglobin amount.
