5 Claims

1. An apparatus for estimating a bio-component, the apparatus comprising:

a Raman sensor comprising:

a light source assembly having a plurality of light sources that are arranged in a circle, and are configured to emit light to a plurality of skin points having a predetermined separation distance from a light collection region of skin from which Raman scattered light is collected

a light collector disposed at a center of the plurality of light sources and configured to collect the Raman scattered light from the light collection region of the skin;

a light reflection surface provided between the light source assembly and the light collector to reflect the light that is emitted from the plurality of light sources toward the plurality of skin points; and

a detector configured to detect the collected Raman scattered light; and

a processor configured to control the Raman sensor, and to estimate the bio-component based on the Raman scattered light detected by the Raman sensor.
