摘　　要：介绍一种利用现代光通讯技术发展的单模光纤和光纤无源器件,以及半导体激光光源和高速半导体探测器构成的激光微位移干涉测试系统。对冲击加载条件下,花岗岩表面的粒子速度及位移进行了测量。实验结果表明:该系统可实时测量高频条件下微弱质点的速度和位移。A laser micro-displacement interferometer system has been developed on the basis of the development of modern optical communication technology. The interferometer consists of single-mode fiber, fiber coupled components , semiconductor laser and high-speed detector. It can measure the real-time velocity histories of the propagation and attenuation of stress wave in the geologic media. The tests of it using the impact load system shows that the interferometer works well for the propagation and attenuation of high frequency stress wave in the geologic media.
