Abstract
A method of monitoring a blood pressure includes: emitting a laser to a blood vessel in a body part; detecting, from the body part, laser speckles caused by scattering of the emitted laser; obtaining a bio-signal indicating a change in a volume of the blood vessel by using the detected laser speckles; and estimating a blood pressure based on the obtained bio-signal.
