Abstract
A sensor is disclosed having one or more light sources, and one or more light detectors. At least one of the detectors produces an output in response to received light. Also, electrical circuitry in response to the output generates a pulse waveform proportional to the arterial and venous pulse of a human body, wherein the pulse waveform is used to synchronize an arterial-pulse measurement of the absorption or reflectance of one or more coherent light sources.
