Non-contact physiological monitoring using image sensors becomes popular for the cutting-edge medical and security applications. This paper reports a multi-tap NIR lock-in CMOS imager which is able to achieve heart rate and its variability measurements under varied ambient light and artificial motion conditions with excellent SNRs.
