摘　　要：光电传感器是将光信号转换为电信号的器件,它具有反应速度快、检测灵敏度高、可靠性好等特点。光电脉搏仪是光电传感器在医学测量中的重要应用。当恒定波长的光线照射到人的身体上之后,人身体组织会自动地吸收和反射光强,根据人体吸收、反射和衰减光强的程度可以反映被照射部位组织的结构性状。2020年,新冠疫情突然暴发,人体五大健康指标分别为血氧饱和度、体温、呼吸频率、心率和血压。文章将从基于光电式传感器的脉搏仪出发,分析其在血氧饱和度和心率检测中的应用。Photosensor is a device that converts optical signal into electrical signal. It has the characteristics of fast reaction speed, high detection sensitivity and good reliability. Photoelectric pulse meter is an important application of photoelectric sensor in medical measurement. When the constant wavelength of light shines on the human body, the human body tissue will automatically absorb and reflect the light intensity, according to the degree of the human body can reflect the structural characteristics of the tissue of the irradiated site. In 2020, the COVID-19 outbreak suddenly erupted, with five major human health indicators: blood oxygen saturation, body temperature, respiratory rate, heart rate and blood pressure. This paper will analyze the application of blood oxygen saturation and heart rate detection from a pulse meter based on photoelectric sensor.
