摘要：

The line-focus-beam acoustic microscope system is applied to investigate the elastic properties of LiTaO3. Elastic inhomogeneities are detected quantitatively as a significant variation of leaky surface acoustic wave (LSAW) velocities in X-112.2-degrees Y LiTaO3 wafers. Large changes, about 2.5%, in LSAW velocities are observed in some wafers, which correspond to a difference between the velocities for single and multidomains. One of the causes is found to be in the poling process during wafer fabrication.
