Abstract
A Raman signal analysis device, which enables miniaturization of the device and non-invasive continuous monitoring of blood glucose level, includes a housing that forms an internal accommodation space therein; one or more light source units that are disposed within the housing and irradiate light onto a subject; a light receiving unit that obtains a Raman signal of light reflected or scattered from the subject using an optical filter array and an optical detection component array; and a processor configured to analyze biological information of the subject based on the Raman signal acquired by the light receiving unit.
Claims9
An apparatus comprising:
- a plurality of light sources, each of which generates light to be irradiated onto a subject, wherein the plurality of light sources output a plurality of different wavelength bands;
- an optical filter that selectively transmits a predetermined wavelength band among light reflected or scattered from the subject;
- a detector that receives the light transmitted from the optical filter and generates electrical signals representative of an amount of the light received;
- and
- a processor configured to analyze biological information associated with the subject based on the electrical acquired by the light receiving unit,
- wherein a difference between each wavelength of the plurality of light sources and the predetermined wavelength band of the optical filter corresponds to at least one Raman shift of a peak in a Raman spectrum, and
- wherein the biological information is obtained based on each of the at least one Raman shift.
