| Abstract: | 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 f... |
