摘　　要：本文介绍了用激光实时全息术测量岩石的泊松比μ;用激光散斑照相放大技术测量岩石的杨氏模量E;电阻应变片法;易于现场应用的岩石弹性参数散斑照相测量法。The application of laser real- time holography and speckle photography amplification to measure the rock elasticity parameters is briefly introduced. The data concluded in interference fringe was analyzed and compared with those from traditional measurement. Measurement results are presented as follows : Poisson' s ratio μ of rock by laser real-time holography, and Young' s modulus E of rock by speckle photography amplification; straining slice of resistance; speckle photography amplification method is easy to measure rock elasticity parameter in practice.
