摘要

近红外血液检测技术中

透射式光电容积脉搏传感器具有携带有效信息量大的优点

可为动态光谱检测理论提供有效采样数据

但实际应用受到个体差异性的限制。为了克服不同手指端厚度给传感器带来的检测难题

分析了检测结果中压力与直流分量及交流分量之间的关系

通过不同厚度的手指测试实验

指出了存在一个最佳检测区域使得检测到的脉搏波处在最理想状态。

Abstract

Being a kind of near-infrared blood detecting technology

although the photoelectric pulse sensor takes advantage of rich payload of effective information

which is able to provide effective sampling data to dynamic spectral detection theory.But its practical application is limited by individual diversity.In order to overcome the detecting problem of different thickness of the finger-sides

the relationship between the pressure and the DC component and AC component in test result is analyzed.Through testing experiments of different finger thickness

the existence of an optimal detection region which allows the pulse wave detected by the sensor in the most ideal state is pointed out.
