Optical measurement instrument for living body |
摘要 |
An optical measurement instrument for living body includes: a plurality of light irradiation means for irradiating an object being tested with light; a plurality of light reception means for detecting the light that is irradiated to the object being tested and propagates inside the object being tested; and a calculation unit for calculating hemodynamics of a plurality of factors inside the object being tested from the detection signal detected by the light reception means, wherein the calculation unit includes a separation calculation unit for separating a plurality of signals from the detection signals; a selection unit for calculating a correlation coefficient between a plurality of the signals separated to select a signal in which a correlation coefficient is a predetermined value or greater as a noise signal; and a reconstruction calculation unit for reconfiguring the detection signal excluding the noise signal selected by the selection unit. |
