In order to more accurately estimate the concentration of triglycerides in the blood through the change of the scattered light signal, it should be that only the scattering coefficient of the blood will cause the change of the scattered light signal, but in fact, in addition to the change of the scattering coefficient of the blood, such as Various noise factors such as physical / chemical changes in the skin, hemodynamic changes, etc. may affect the scattered light signal

An apparatus for non-invasively measuring bio-information is provided. The apparatus includes a plurality of light sources configured to emit light to a first region and a second region of an object,a detector configured to detect a first scattered light signal from the first region and a second scattered light signal from the second region and output a first electrical signal corresponding to the first scattered light signal and a second electrical signal corresponding to the second scattered light signal, and a processor configured to correct the first electrical signal based on the secondelectrical signal and measure bio-information based on a correction result.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0164565 filed in the Korean Intellectual Property Office on December 1, 2017, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] Exemplary embodiments of the present disclosure relate to an apparatus and method for non-invasively measuring biological information, and more particularly, to a technique for measuring biological information by correcting noise in information about a blood vessel region based on information about a non-vascular region. Background technique [0004] Typically, the non-invasive method of measuring triglyceride levels is to estimate the concentration of triglycerides in blood by placing a measurement device consisting of a light source and an optical sensor on a blood vessel and measuring the scattered light signal passing through the blood. Since the change in ...
