摘要
利用干涉仪原理和多普勒效应,设计出基于干涉仪的新型多普勒效应测量装置。分析了测量装置工作原理及调整步骤,利用该装置设计了激光多普勒速度与音频辨别实验,以及多普勒效应中反射镜运动速度的测量实验。该测量装置拓展了干涉仪在科研和实验教学中的用途,为研究多普勒效应提供了新的思路和方法。
The interference principle and characteristics of Doppler effect are preliminarily analyzed and studied. On the basis of interferometer, a new type of Doppler effect measuring device is designed. The principle and adjustment steps of the measuring device are analyzed. The experiment of the speed and audio discrimination of the laser Doppler radar is carried out by the device. And the experiment of measuring the movement speed of the mirror in the Doppler effect is carried out. The combination of interferometer and Doppler effect is extended to its application in the research and teaching. New idea and method is provided for the study of the Doppler effect.
