| Abstract: | The experimental method of pulsed laser holography, which is applied to the study of stress waves in explosion, has been used in this paper. The holographic interference patterns of the surface displacements caused by stress waves in explosion, has been obtained in 3D model. Through analysis and calculation of the interference fringe patterns,it has been found that the surface vibration caused by small amount of charge decreases with the increase of the burying depth of the charge. |
