摘要：
A photoplethysmography apparatus is provided. The photoplethysmography includes a plurality of light-emitting units spaced apart from each other and configured to emit light to a measurement part, a light-receiving unit disposed in the center of the light-emitting units and configured to detect transmitted or reflected light from the measurement part by the light-emitting units, a signal pre-processing unit configured to amplify and filter a measurement signal of the light-receiving unit, and a signal processing unit configured to extract a heart rate of a target person using an output signal of the pre-processing unit. The light-emitting units and the light-receiving unit provide a plurality of optical paths, and the light-receiving unit detects spatially averaged reflected or transmitted light at the measurement part.
