Abstract: Single beam laser speckle photography can provide the poisson's ratio and Young's modulus of rock samples.The experimental results are compared with those of some typical methods for determining the elastic parameters of rocks. The suggested experimental method requires simple equipment, its accuracy satisfies the requirement of petroleum industry,and it is convenient for field application.
