摘　　要：本文简要阐述了全息照相术的原理及会聚冲击波的特点，在此基础上，设计了一种二次曝光全息照相干涉系统，使用该系统对圆柱形冲击波会聚过程的不稳定性进行了观测，得到了清晰的干涉图像，给出了几个重要结论。In this paper, principle of holographic interfering technology and characteristics of the converging cylindrical shock waves are introduced. A double\|exposure holographic interferometer is designed. The system and gets visualizes the instability of the converging cylindrical shock waves, sequential interferograms are show. A few important conclusions are proposed.
