Abstract
A Raman sensor includes a light source assembly having a plurality of light sources configured to emit light to a plurality of skin points of skin, each of the plurality of skin points having a predetermined separation distance from a light collection region of the skin from which Raman scattered light is collected; a light collector configured to collect the Raman scattered light from the light collection region of the skin; and a detector configured to detect the collected Raman scattered light.
Claims5
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.
An apparatus for estimating a bio-component, the apparatus comprising:
- a first light source configured to emit light toward a first skin point of skin having a first predetermined distance from a light collection region of the skin from which Raman scattered light is collected by a light collector;
- a second light source configured to emit light toward a second skin point of the skin having a second predetermined distance from the light collection region of the skin from which the Raman scattered light is collected by the light collector;
- the light collector that are provided between the first light source and the second light source, and are configured to collect the Raman scattered light from the light collection region of the skin;
- a first light reflection surface that is provided between the first light source and the light collector to reflect the light that is emitted from the first light source toward the first skin point;
- a second light reflection surface that is provided between the second light source and the light collector to reflect the light that is emitted from the second light source toward the second skin point;
- a detector configured to detect the collected Raman scattered light;
- and
- a processor configured to estimate the bio-component based on the detected Raman scattered light.
