OPTICAL MEASUREMENT INSTRUMENT FOR LIVING BODY
First Claim
1. An optical measurement instrument for a living body, comprising:
- 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 said object being tested and propagates inside said object being tested; and
a calculation unit for calculating hemodynamics of a plurality of factors inside said object being tested from the detection signal detected by said light reception means,wherein said calculation unit comprises;
a separation calculation unit for separating a plurality of signals from said detection signal;
a selection unit for calculating a correlation coefficient between a plurality of said signals separated by said separation calculation unit to select a signal in which said 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 said selection unit.
