1. A Raman signal analysis device, comprising:
a communication unit;
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,
wherein, in response to the Raman signal analysis device being worn on a user's body, the processor is configured to control the one or more light source units and the light receiving unit to perform calibration,
wherein, when the calibration is performed, the processor is configured to:
control the one or more light source units to output the light at a predetermined intensity during a predetermined time period; and
set a light amount and an exposure time for the one or more light source units for measuring blood sugar based on a peak corresponding to a specific Raman transition value among the Raman spectrum acquired during the predetermined time period by the light receiving unit,
wherein, when the calibration is performed, the processor is configured to, in response to the Raman signal intensity corresponding to the specific Raman transition value not reaching a reference value even with the one or more light source units having reached the light amount and the exposure time, cause the communication unit to transmit an error message, and
wherein the error message includes a message requesting a change of an attachment site or re-attachment of the device.
