Abstract
A variable wavelength generating method and an apparatus thereof, for use in measuring a body fluid constituent concentration. The apparatus includes: a thermo-electric cooler (TEC) whose temperature is varied depending on a change in a supplied current; a light source section generating a wavelength that is varied depending on a temperature change of the thermo-electric cooler; a current supply control section controlling a current supplied to the TEC; an operation power source generation section supplying an operation power source for performing synchronization so that an operation of the light source section may be performed; and a controller for adjusting a current flowing in the TEC adjusting the operation power source supplied to the light source section.
