摘要
应用单周期层栅和基于旋转场辨别速度方向的激光多普勒测振系统是近年来研制出的一种新型测速手段。本文在阐述测量原理的基础上,重点介绍了本系统的光学、光电转换、频压转换以及微机信号处理等各组成部分,综述理论与实验研究成果。
By means of single-cycle layer grating, the laser Doppler vibration measur-ing system discriminating velocity orientation by rotating field is a new velocitymeasuring instrument developed in recent years.Based on the description ofmeasuring principle, the optics of the system, photoelectric conversion, frequen-cy-pressure conversion and signal processing by microcomputer are emphaticallypresented. Theoretical and experimental results are summerized.
