后向散射激光多普勒测速仪的实验研究

The experimental research of laser Doppler velocimeter in backscatter

设计了一种后向散射激光多普勒测速实验装置并成功地用于风速测量。此装置结构简单,操作方便,既可用于远距离流场测量,又可用于大型燃烧炉和内燃机中的速度测量。

An experimental device of laser Doppler velocity measurement in backscatter has been designed and used successfully for measurement of particle velocities. The device has simple structure and can be operated conveniently. It can be applied to remote measurement of flow field, and measurement of particle velocities in larger combustors and inter engine as well.
