介绍了一种采用实时频谱分析的激光多普勒测速仪的自动速度跟踪电路。该电路通过跟踪频谱分析仪输出上选定强度级的交叉位置来提供与速度成正比的模拟电压。给出了在原生质流和模拟血流动力学研究中的应用实例。
A circuit is described which will adapt a laser Doppler velocimeter using real‐time spectrum analysis for automatic velocity tracking. The circuit provides an analog voltage which is proportional to velocity by tracking the position of crossing of a selected intensity level on the spectrum analyzer output. Examples of applications to the study of protoplasmic streaming and simulated hemodynamics are presented.
