激光全息干涉法在岩石裂隙研究中的应用

Application of Laser Holographic Interferometry in the Study of Rock Fissure

阐述了激光全息干涉计量技术在岩石裂隙实验测量中的应用，完整地获得了板岩试样裂隙开起、扩展、破坏全过程的实时全息干涉图谱，形象、直观、高精度地显示出板岩试样内部裂隙的变化规律，这是常规实验难以实现的。

This paper expounds the application of Laser Holographic interferometry in the laboratorial measurements of rock fissure. Instant hologram in the whole process of slates fissure starting. expanding and cracking is obtained completely Hologram of image. object and high accuracy shows the laws of inner fissure changes in slates.It is difficult to realize in normal laboratorial method.
