Abstract
A biological component measuring apparatus may include: a first light source configured to emit a first light of a first wavelength range onto an object; a second light source configured to emit a second light of a second wavelength range onto the object, the second wavelength range being different from the first wavelength range; a detector configured to detect the first light and the second light which are scattered from the object; and a processor configured to determine a scattering coefficient based on the detected first light, obtain blood vessel depth information based on the detected second light, and measure a biological component by correcting the scattering coefficient based on the blood vessel depth information.
