本文介绍用动态相位计作为激光多普勒振动传感器的信号处理系统。所测振动频率范围为0～20KHz,测速度范围为0.01μm/s～300mm/s。该系统已用于测量计算机硬盘磁头起飞的动态过程。
This article describes the use of dynamic phase meter as a laser Doppler vibration sensor signal processing system. The measured vibration frequency range of 0 ~ 20KHz, speed measurement range of 0.01μm / s ~ 300mm / s. The system has been used to measure the dynamic process of taking off the head of a computer hard disk.
