We present a novel technique for remote noncontact blood pulse pressure measurement. It is based on tracking both temporal and amplitude changes of reflected secondary speckle produced in human skin when illuminated by a laser beam. The implemented technique extracts the difference between the systolic and the diastolic blood pressure. Experimental results are presented showing good agreement when compared with conventional measurement methods.
我们提出了一种新颖的远程非接触式血压脉搏测量技术。它基于跟踪激光束照射在人皮肤上产生的二次散斑的时间和幅度变化。所实现的技术提取了收缩压和舒张压之间的差异。实验结果表明，与传统测量方法相比，该方法具有良好的一致性。
