Optical system for measuring metabolism in a body |
摘要 |
The invention provides optical technique for measuring metabolism in a living body that can further reduce an error in measurement even if distance between irradiation and detection is fixed. The living body is classified into measurement regions and different measuring wavelengths are set according to the classification. For example, the head is classified into four regions of a parietal region, a frontal region, a temporal region and an occipital region and a wavelength according to each tissue is set in a wavelength selecting system. In measurement, wavelengths according to each measurement region are selected by multiple wavelengths-light radiating means. Besides, for a region having large personal difference, premeasurement is made using plural combinations of wavelengths and wavelengths are selected using a calculated error in measurement as a criterion.
