In this paper, the real-time holographic method is introduced to the basic seismic experiment. In the experiment, the rupture process of uniform rock mass is simulated by the compressive rupture process of transparent specimen. The real-time holographic interferographic system is used to record the stress field distribution and its variation Transient waveform automatic recording system records the location and intensity of micro-cracks. The data obtained by the two methods are used to explore the relationship between the micro-cracking nucleation process and the stress field. The success of this method provides a new method for seismic experiment research.
