Abstract

A method for measuring heart rate is provided. The method includes illuminating a body portion with light, detecting light scattered by tissues of the body portion and blood particles by a plurality of photodetectors including at least one pair of photodetectors which are connected in anti-parallel in each pair of photodetectors, eliminating a frequency component of motion artifacts in an analog photocurrent differential signal by subtracting a first analog photocurrent signal detected by a first photodetector of a pair of photodetectors of the at least one pair of the photodetectors from a second analog photocurrent signal detected by a second photodetector of the pair of photodetectors, converting the analog photocurrent differential signal into an analog voltage differential signal, converting the analog voltage differential signal into a digital differential signal, calculating an envelope of the digital differential signal, and calculating the heart rate from peaks of the calculated envelope of the digital differential signal.
