| Summary: | We propose a new method for measuring velocities and polarizations of the compressional and shear waves. The method consists of measuring time dependent displacement of a particular point on the sample surface in three independent directions by a laser Doppler interferometer. The high accuracy of these measurements makes the determination of the polarization straightforward, and thus the identification the type of the waves unambiguous. These measurements can be used to estimate the stiffness tensor of anisotropic rock samples. |
