Abstract: An optical device 1 includes: an optical element block 10 including optical elements that form an optical path P of light used for optical measurement, arranged around a measurement subject S so that the optical path P intersects the measurement subject S; and a rotation mechanism 20 configured to change an angle of the optical element block 10 relative to the measurement subject S so that the total length of the portion of the optical path P coincident with the measurement subject S changes.

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.
