摘要
采用双波长760nm和850nm的近红外光进行脑血氧检测,能够无损、实时、连续获得脑血氧信息。首先推导出双波长数理模型,该模型只需测一个参数光强吸收比率n,其次选取波长,确定源标距,最后通过简单的憋气试验验证了该方法的有效性。
Brain blood-oxygen detecting use dual. wavelenght near infrared light,760nm and 850nm,which can noninvasively, real-time, continuously monitor brain blood-oxygen information. Firstly, the dual wavelenth math and physics model was deduced, and this model need only measure one parameter which is light intension absorption rate n. Secondly, the wavelengths and source-target distance were choosed. At last, the experiment of holding one＇s breath proved the validity of the method.
