摘　　要：传统的组织血氧含量测量方法是有创测量,且很难做到连续测量。因此,利用近红外光谱无创技术监测血氧含量就越来越成为世界范围内研究的热点;血氧浓度信号因本身微弱、受干扰大,光子在组织内传播具有随机性,致使检测困难很大。文中就近红外光谱技术监测血氧含量提出了一种硬件设计思路。The conventional invasive tissue blood oxygen content measurement is poor in continuity. The weakness of the signal, strong interference and random transmission of the photon in tissues make the measurement difficult. Recently, near infrared spectrum technology has been applied to tissue blood oxygen content measurement. This paper presents a hardware design method for tissue blood oxygen content measurement by near infrared spectrum technology.
