Continuous noninvasive measurement of vital bio-signs, such as cardiopulmonary parameters, is an important tool in the evaluation process of the patient's physiological condition and in the health monitoring of the patient. On the demand of new enabling technologies, some works have been done in continuous monitoring of blood pressure and pulse wave velocity. In this paper, we introduce further application of a novel technique for remote noncontact blood pulse wave velocity and pressure measurement based on tracking the temporal changes of reflected secondary speckle patterns produced in human skin when illuminated by a laser beam. The main goal of this work is to offer novel, simple and low cost measurement tool which will indicate changes in condition of the cardiovascular system after having an initial calibration.
连续无创测量重要的生命体征，如心肺参数，是评估患者生理状况和健康监测过程中的一项重要工具。随着新使能技术的需求，在血压和脉搏波速度的连续监测方面已经开展了一些工作。在本文中，我们介绍了一种基于跟踪激光束照射人体皮肤时产生的反射二次散斑图案的时间变化的新型远程非接触式血脉搏波速度和压力测量技术的进一步应用。这项工作的主要目标是提供一种新颖、简单且低成本的测量工具，该工具在进行初始校准后将指示心血管系统状况的变化。
