By means of combining the real-time holographic device and the acoustic source testing device, a new tool for experimental earthquake simulation research is developed. The stress fields and its variations in the specimen are recorded by real-time holographic interferometry while the wave-forms of ultra-sonic waves stimulated by the micro-cracks are recorded by a transient automatic wave-form recorder to determine the time, location and intensity of the micro-cracks. Some noticeable phenomena have been observed in the experiment, the elastic strain and plastic strain can be visualized clearly and can be recorded in high resolution by this method as well as the generation and extending of cracks.
