摘要
光电容积描记法(PPG)有效利用了光电技术的最新发展及应用成果,借助光电手段,通过检测生物组织血液容积的变化来获得人体生理学信号及特征。它是一种非侵入式测量技术,可广泛用于个人、家庭及大规模人群的生理健康检测和监测。近年来,对PPG及其应用的研究已经成为生物医学工程领域研究的热点问题之一。本文探讨了PPG的光学原理和技术特征,并对其在生理学监测中的应用以及未来发展进行了系统的综述。
The electro-optic technique of measuring the cardiovascular pulse wave, known as photoplethysmography （PPG）, is clinically utilised for noninvasive characterisation of physiological components by dynamic monitoring of tissue optical absorption. Non-invasive PPG technology has been used in a wide range of individual, home or public health monitoring. The application of PPG has become one of the hot topics in the fields of biomedical engineering recently. This paper reviews the optical origins of PPG signal, the feature of PPG technology, the applications of PPG in physiological measurements and its development in the future.
