| Abstract: | In order to monitor the process of the laser shock processing and the effect of laser shock processing on the materials,amethod of plasma acoustic wave diagnosis is discussed. Analyzing the energy distribution and the relativity of the plasma acousticwave using the wavelet packet analysis, the frequency characteristics of the plasma acoustic wave and the effect of the limiting layeron the plasma acoustic wave were concluded. |
