Abstract: An apparatus for obtaining bio-information may include a pulse wave sensor including a light source and a detector. The light source is configured to emit multi-wavelength light to an object of interest and the detector is configured to detect light reflected from the object. In addition, the apparatus may include a processor configured to obtain a change in volume of a blood vessel based on one or more of quantity of detected multi-wavelength light and absorbance coefficients of respective wavelengths of the multi-wavelength light and obtain bio-information based on the measured change in volume of the blood vessel.

Abstract: An apparatus for non-invasively measuring bio-information is provided. The apparatus includes a plurality of light sources configured to emit light to a first region and a second region of an object, a detector configured to detect a first scattered light signal from the first region and a second scattered light signal from the second region and output a first electrical signal corresponding to the first scattered light signal and a second electrical signal corresponding to the second scattered light signal, and a processor configured to correct the first electrical signal based on the second electrical signal and measure bio-information based on a correction result.
