激光多普勒测量技术及其应用

Laser Doppler Measuring Technique and Its Application

从光学结构、信号处理、方向辨别三个方面综述了激光多普勒测量技术的研究，最后讲述了激光多普勒测量技术在散射体位移测量中的一个实际应用──空间滤波的仿光栅散射体多普勒测量。

The paper generalizes the study of laser Doppler technique from the aspects which include optical system. signal proccssing and directlon distinguishing. An application of laser Doppler measurement system to the scatlerer displacement is thcn described, which imitates the grating Doppler effect by space filter.
