Abstract
An apparatus for measuring a biological component includes: light sources configured to emit light that irradiates a target object; one or more detectors configured to receive light from the target object that is irradiated by the light emitted by the light sources and to detect light signals corresponding to the light received from the target object; and a processor configured to determine an optimal light source for measuring a biological component, from among the light sources, based on the light signals detected by the one or more detectors and to measure a biological component of the target object using the optimal light source.

An apparatus for measuring a biological component, the apparatus comprising:
- light sources configured to emit light that irradiates a target object;
- detectors configured to receive light from the target object that is irradiated by the light emitted by the light sources and to detect light signals corresponding to the light received from the target object;
- and
- a processor configured to determine an optimal light source, from among the light sources, based on the light signals detected by the detectors and to measure a biological component of the target object using the optimal light source,
- wherein the processor comprises a detector determiner configured to determine two optimal detectors for measuring the biological component, from among the detectors, based on signal-to-noise ratios of light signals detected by the detectors, and
- wherein the processor further comprises a component measurer configured to determine a scattered coefficient based on backscattered light intensities of light signals detected by the two optimal detectors and to measure the biological component of the target object based on the scattered coefficient.
A method of measuring a biological component, the method comprising:
- receiving, at detectors, light from a target object that is irradiated with light by light sources;
- detecting, at the detectors, light signals corresponding to the light from the target object;
- determining an optimal light source of the target object, from among the light sources, based on the light signals detected by the detectors;
- and
- measuring a biological component of the target object using the optimal light source,
