激光多普勒测速实验的研究分析

Experimental Studies of Laser Doppler Velocimetry

激光多普勒测速实验是基于A-D转换原理,将光信号转换为电信号从而测量斩波器的转动速度。实验要求正确调节光路,理解多普勒原理,学会客观、准确的分析实验现象。文章介绍了实验的基本原理和操作步骤,通过对实验数据的处理分析对实验提出了改进意见。

Laser Doppler identification experiment which based on conversion principle,translates optical signal into electrical signal and to measure the rotation speed of the chopper.The experiment is required to adjust correctly light path,understand the Doppler principle and master to analyze objectively the experiment phenomenon.This paper introduces the basic principle and the operation steps,in addition according to the analysis of the experimental process,give some personal opinions.
