Abstract: An apparatus (100) for estimating bio-information, includes: a sensor (110) configured to detect at least one first light signal and at least one second light signal, each of the at least one first light signal having a first light path from an object and each of the at least one second light signal having a second light path from the object that is different from the first light path; and a processor (120) configured to: obtain a first absorbance based on the at least one first light signal, obtain a second absorbance based on the at least one second light signal, and estimate bio-information based on a difference between the first absorbance and the second absorbance.
