A method to determine elastic constants of high acoustic velocity materials by line-focus acoustic microscopy is presented. To determine elastic constants the distances between the specular reflection peak and the first interference maximum and minimum of the V(z) curve measured by line-focus acoustic microscopy were compared to the corresponding distances obtained from a V(z) measurement model that simulates the experiment. Elastic constants of a single-crystal diamond sample were determined by this method.
